Abstract
Dioxomolybdenum(VI) and oxotungsten(VI) complexes with a new amine bisphenol ligand (H(2)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(2)(acac)(2)] yielded a monomeric molybdenum complex [MoO(2)(L)(MeOH)] (2a) or a dimeric complex [Mo(2)O(2)(mu-O)(2)(L)(2)] (2b), depending on the reaction conditions. The reaction with a tungsten trisglycolate [W(eg)(3)] led to the formation of a monomeric compound [WO(eg)(L)] (3). 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 2a was investigated by X-ray crystallography.
