Molybdenum hexacarbonyl, or Mo(CO)6, is a metal carbonyl containing molybdenum in its +6 oxidation state. It is a dark brown solid that decomposes in moist air to give volatile products. It is soluble in carbon disulfide and other organic solvents. Mo(CO)6 was one of the first metal carbonyls to be prepared and characterized. It was first prepared by German chemist Carl Wilhelm Scheele in 1782 by reduction of molybdic oxide with carbon monoxide.

The structure of Mo(CO)6 has been determined by X-ray crystallography. It features octahedral Mo(CO)6 units that are interconnected by sharing edges. The Mo-C bond lengths are 1.79 Å and the C-O bond lengths are 1.43 Å.

The preferred method for the preparation of Mo(CO)6 is by reduction of molybdic oxide with carbon monoxide at 350-450 °C:

2MoO3 + 3CO → Mo(CO)6 + 3CO2

An alternative route involves the reaction of sodium molybdate with hexacarbonylchromium:

Na2MoO4 + 2Cr(CO)6 → Mo(CO)6 + 2NaCr(CO)4 + 2CO2


Compounds of molybdenum are frequently very colorful, for example Mo(CO)6 is red. Molybdenum compounds tend to be oxidized easily, giving green or blue solutions. The color of these solutions arises from ligand-to-metal charge transfer transitions. The starting material for the production of most molybdenum chemicals is the mineral molybdenite (MoS2). Molybdenum metal is produced by reducing molybdenum hexachloride with hydrogen:

2 MoCl6 + 12 H2 → 2 Mo + 12 HCl 

The main impurity in this product is iron, which can be removed by electrolysis. Molybdenum has one of the highest melting points of all pure elements (2623 °C). The melting point of molybdenum also depends on the purity of the metal; the more impurities, the lower its melting point. For this reason, molybdenum is often used as an alloying agent in steels and cast irons. When added to steel, molybdenum increases strength, hardness, and resistance to wear and heat. It is also used in superalloys for parts that must operate at high temperatures, such as jet engine turbine blades.

mo(co)6 oxidation number

In chemistry, the oxidation number of an element is a measure of the degree of oxidation of that element. In most cases, the oxidation number of an element is equal to the charge that the element would have if it were ionic. For example, the oxidation number of sodium is +1, and the oxidation number of chlorine is -1. However, there are some elements that can have multiple oxidation numbers. For instance, oxygen typically has an oxidation number of -2, but it can also be +2 in peroxides and +1 in superoxides. The same is true of sulfur: its most common oxidation state is -2, but it can also be +4 or +6 in some compounds. Finally, carbon usually has an oxidation state of -4, but it can also be +2 in carbides or +4 in carbenes. As you can see, understanding oxidation numbers is essential for correctly identifying the composition of many compounds.


Mo(CO)5 is a complex compound of molybdenum and carbon, containing both metal and non-metal atoms. The compound is commonly used as a catalyst in chemical reactions, due to its unique properties. For example, Mo(CO)5 is able to speed up the formation of new bonds between atoms, while also breaking existing bonds. This makes it an ideal catalyst for reactions that involve the formation of new molecules, such as in the synthesis of drugs and other chemicals. In addition, Mo(CO)5 is highly soluble in both organic and inorganic solvents, making it suitable for use in a wide range of industrial processes.

mo(co)6 shape

The shape of a molecule is determined by the location of the atoms that make it up. In the case of mo(co)6, the six molybdenum atoms are arranged in a octahedral shape. This means that each atom is surrounded by eight others, arranged at 90-degree angles. The octahedral shape is common in molecules containing transition metals, and provides stability by minimizing the repulsion between atoms. The mo(co)6 molecule has a similar structure to other molybdenum compounds, such as mo(cn)6 and mo(cr)6. However, the octahedral shape is not always possible; in some cases, atoms may be arranged in a trigonal bipyramidal shape or a square planar shape. The shapes of molecules are constantly changing as atoms move around and bond with one another. By understanding the forces that hold molecules together, chemists can predict and control their properties.

mo(co)6 lewis structure

What is Sodiums oxidation number?

Sodium’s oxidation number is +1. This means that sodium has lost one electron, leaving it with a positive charge. Sodium is a highly reactive element, and this reactivity is due to the fact that it only has one electron in its outermost orbital. This makes it very easy for sodium to lose that electron and form a positive ion. Sodium is found in many compounds, such as table salt (NaCl), where it forms a stable ionic bond with chlorine. However, sodium can also be dangerous because of its reactivity. When sodium comes into contact with water, it forms hydrogen gas (H2) and explodes. This is why sodium must be kept away from moisture and stored in an airtight container.

What is D2h point group?

What is c2v symmetry?

In chemistry, c2v symmetry is a type of point symmetry in which an object has two types of mirror planes, each containing two perpendicular axes of rotation. The “c” stands for “cylindrical” and the “v” for “vertical”, referring to the orientation of the mirror planes. This type of symmetry is common in molecules with linear geometry, such as carbon dioxide (CO2). In addition to the two mirror planes, c2v symmetry also has a molecular axis of rotation, which runs parallel to the molecular plane. This axis is known as the principle axis of rotation. The threefold axis of rotation is perpendicular to the molecular plane and intersects the center of mass. It is known as the inverse operation or improper axis of rotation. C2v symmetry can be classified into two subgroups: Cs and Ci. The Cs subgroup has one type of inversion symmetry (I), while the Ci subgroup has no inversion symmetry (i). In other words, Ci molecules are chiral, while Cs molecules are achiral. C2v symmetry is often used to predict the shapes of molecules and identify their possible optical isomers.

What is D4h symmetry?

In mathematics, a symmetry of an object is a physical or abstract characteristic of the object that remains unchanged under certain transformations. An object with D4h symmetry, such as a square, has eightfold rotational symmetry and reflection symmetry along four perpendicular axes of rotation. In other words, it can be rotated by 90 degrees eight times (2Pi/8 radians) and still look the same, and it can be reflected in any of four perpendicular planes and still look the same. The “D” in D4h stands for “dihedral,” meaning that the object has twofold rotational symmetry (like a top), and the “h” stands for “horizontal,” meaning that it also has reflectional symmetry in horizontal planes (like a mirror). Therefore, D4h is sometimes also called C4v symmetric point group, after its point-group notation. Square is the only shape with D4h symmetry; however, there are many molecules with this type of symmetry.

Where does Molybdenum come from?

Molybdenum is a mineral that can be found in small amounts in nearly all rocks and soil. However, it is relatively rare in its pure form, and most molybdenum is extracted as a by-product of copper or nickel mining. The largest deposits of molybdenum are found in the United States, China, and Chile. However, due to the high demand for molybdenum, these deposits are quickly being depleted. As a result, mining companies are increasingly looking to places like Russia and Canada for new sources of molybdenum. In addition to its uses in industry, molybdenum is also an essential nutrient for plants and animals. For humans, it plays a role in metabolism and the development of bone tissue. A lack of molybdenum can lead to problems such as anemia and birth defects. As a result, it is important to ensure that there is enough molybdenum in the diet. Good sources of molybdenum include legumes, whole grains, and leafy greens.
