Abstract

By employing low temperatures it has been found possible to isolate diamagnetic oxotungsten(VI) complexes, [WOCl 4L] (L = PPh 3, PPh 2Et, OPPh 3) and [WOCl 4L 2] (L= PPh 3, PEt 3, PPr 3 n , OPPh 3), by the reaction of WOCl 4 with the ligands. Attempts to isolate analogous phosphine complexes of oxomolybdenum(VI) resulted in reduction to molybdenum(V). The [WOCl 4L] complexes are assigned a six-co-ordinate structure containing the trans-OWL moiety; the[WOCl 4L 2] are assigned a seven-co-ordinate structure. In addition the seven-co-ordinate [WOCl 4(aa)] (aa = o-phenylenebisdiphenylarsine) has been isolated.
