Abstract
The thermal decompositions of [MoO3(2,2'-bipy)], [Mo2O6(2,2'-bipy)], and [M o3O9(2,2'-bipy)(2)] have been studied by Raman spectroscopy. Upon heating, [MoO3(2,2'-bipy)] loses 2,2'-bipyridine and converts to MoO3 through a stab le intermediate, [Mo2O6(2,2'-bipy)], whereas [Mo3O9(2,2'-bipy)(2)] loses 2, 2'-bipyridine and transforms to MoO(3)directly. Vibrational assignments for [Mo3O9(2,2'-bipy)], [Mo2O6(2,2'-bipy)], and [Mo3O9(2,2'-bipy)(2)] are prop osed.
