Coordination complexes of the tungsten(VI) oxide fluorides WOF4 and WO2F2 with neutral oxygen and nitrogen donor ligands

Phosphine and diphosphine complexes of tungsten(VI) oxide tetrafluoride

Six-co-ordinate complexes of the type WCl4(ligand)2 and WCl4(bidentate) and the apparently seven-co-ordinate [WCl4(Me3N)3] have been obtained from [WCl4(RCN)2] under mild conditions. Reduction to polymeric tungsten(III) compounds occurs under more vigorous conditions. The bidentate o-phenylenebisdimethylarsine forms a number of complexes, including the seven-co-ordinate [WCl5(diars)] and [WOCl4(diars)]. However no evidence for eight-co-ordinate [MCl4(diars)2] or [MCl4(diars)2]+(where M is Mo or W) could be obtained.
