• Description: Molybdenum (II) acetate is a coordination compound with the formula Mo2(O2CCH3)4. It is a yellow, diamagnetic, air-stable solid that is slightly soluble in organic solvents. Molybdenum(II) acetate is an iconic example of a compound with a metal-metal quadruple bond.
• Physical properties: Molybdenum (II) Acetate adopts the same Chinese lantern structure as related acetate dimers such as rhodium (II) acetate, copper (II) acetate, and chromium (II) acetate. Each Mo(II) center in Mo2(O2CCH3)4 has four d valence electrons. These eight d-electrons form one σ, two π bonds, and one δ bond, creating a bonding electron configuration of σ2π4δ2. Each of these bonds are formed by the overlapping of pairs of d orbitals.The four acetate groups bridge the two metal centers. The Mo-O bond between each Mo(II) center and O atom from acetate has a distance of 2.119 ?, and the Mo-Mo distance between the two metal centers is 2.0934 ?.
• Uses: Molybdenum(II) acetate dimer is generally used as an intermediate compound in a process to form other quadruply bonded molybdenum compounds.
