N2 - Oxomolybdenum (V) complexes of the type (LH)2-[moocl5], (LH)2 [MoOC]4.OH], (LH) [MoOCl4.H2O], [Mo2O4Cl- (l-h)l' (H2O)2].nH2O, (where L = benzimidazole, 2 — α - hydroxymethyl benzimidazole, 2 — α — hydroxyethyl benzimidazole and 2 - α - hydroxybenzyl benzimidazole, L' = EtOH or H2O and n - 0, 1 or 2); [MoOCl3(L)]H2O,(L = benzimidazole); [moocl2(L — H)h2o].H2O, (where L=2-α- - hydroxymethyl benzimidazole) and [mo2O4Cl2L2].2H2O (where L”□ 2-acetyl benzimidazole, 2 - benzoyl benzimidazole and 2 -{o - aminophenyl } benzimidazole) have been isolated and characterised. All monomeric complexes show absorptions in the visible region (~ 710 nm and ~ 440 nm) characteristic of octahedral Mo(V) complexes. The dimeric complexes do not absorb in the visible region, possibly due to the presence the Mo2O4 2+ core. All complexes show an JR absorption band in the region 950 - 1000 cm-1 characteristic of terminal Mo =O. Thermal stabilities of some of the complexes are reported.
