Molybdenum acetate is a chemical compound of molybdenum from the group of acetates with the dimeric constitutional formula [Mo (CH 3 COO) 2 ] 2 .
Extraction and presentation
Molybdenum acetate can be obtained by reacting molybdenum hexacarbonyl with an excess of glacial acetic acid to which a small amount of acetic anhydride has been added.
properties
Molybdenum acetate is a diamagnetic, flammable solid that is in the form of yellow crystal needles. It is practically insoluble in water and insoluble in practically all common solvents. Slow decomposition takes place at room temperature even under protective gas. It is extremely sensitive to moisture and forms a green hydrate. The connection has a triclinic crystal structure with space group P 1 (space group no. 2) .
