Abstract

Dioxomolybdenum(VI) and oxotungsten(VI) complexes with a new amine bisphenol ligand (H<sub>2</sub>L) are reported. The ligand which carries a neutral nitrogen atom, two phenolic oxygen atoms and a thiophene side-arm was synthesized by a simple one-pot Mannich reaction. Further reaction with [MoO<sub>2</sub>(acac)<sub>2</sub>] yielded a monomeric molybdenum complex [MoO<sub>2</sub>(L)(MeOH)] (<b>2a</b>) or a dimeric complex [Mo<sub>2</sub>O<sub>2</sub>(μ-O)<sub>2</sub>(L)<sub>2</sub>] (<b>2b</b>), depending on the reaction conditions. The reaction with a tungsten trisglycolate [W(eg)<sub>3</sub>] led to the formation of a monomeric compound [WO(eg)(L)] (<b>3</b>). In these complexes, the potentially tetradentate amine bisphenolate dianion coordinates as a tridentate O,N,O donor while the sulfur side-arm donor remains intact. The solid-state structure of <b>2a</b> was investigated by X-ray crystallography.
