Abstract

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.
