Tetrakis[μ-(acetato-O:O')]dimolybdaen

BeschreibungMolybdenum (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.

VerwendenMolybdenum(II) acetate dimer is generally used as an intermediate compound in a process to form other quadruply bonded molybdenum compounds.

synthetischeMo2(O2CCH3)4is prepared by treating molybdenum hexa carbonyl (Mo (CO)6) with acetic acid. The process strips CO ligands from hexacarbonyl results in the oxidation of Mo (0) to Mo (II). 2 Mo(CO)6 + 4 HO2CCH3 → Mo2(O2CCH3)4 + 12 CO + 2 H2 Trinuclear clusters are byproducts. The reaction of HO2CCH3 and Mo(CO)6 was first investigated by Bannister et al. in 1960. At the time, quadruple metal-metal bonds had not yet been discovered, so these authors proposed that "Mo(O2CCH3)2 was tetrahedral. This perspective changed with Mason's characterization .
