Use
Molybdenum(IV) oxide can be prepared by several methods including controlled oxidation of Mo and controlled reduction of MoO3 with hydrogen. The pure oxide suitable for structure determination has been prepared by electrolysis of a polymolybdate (K2O5.MoO3) solution. Molybdenum(IV) oxide is insoluble in water: it is inert in solutions of nonoxidizing acids or bases, but is dissolved by oxidizing solutions. It dissociates to Mo and MoO3 at high temperatures (~ 1100).Crystalline MoO2 is violet or brown. Its deformed rutile structure consists of infinite chains of MoO6 octahedra sharing opposite edges along the chain direction with Mo-Mo distances alternately long (3.10 A) and short (2.50 A). It is diamagnetic and semiconducting ; metal-metal bonds are present. Some of its thermodynamic properties are as follows: Gf29% ~ 172.415 kcal/mole Hf29% -140.5 kcal/mole S298 11.954 gibbs/mole.
