ChemInform Abstract: Preparation and Characterization of Mononuclear Organoimido Complexes of Tungsten: X‐Ray Crystal Structures of (WCl4(NC6H4Me‐p)(thf)), (P(CH2Ph)Ph3) (WCl5(NC6H4Me‐p)), and (WCl2(NPh)2(bipy)).

Abstract

275ChemInform Abstract The mononuclear organoimido-W(VI) complexes (I)-(IV) are prepared according to the scheme and characterized by spectroscopic (IR, 1H, 13C NMR) data as well as by X-ray structure analysis of the title complexes (Ia) (space group P21/n, Z=4), (IIa) (P21/a, Z=4), and (IIIa) (P1, Z=4). Correspondingly, the imido-W(V) complexes (XII) are obtained starting with (WCl4(NPh))2 (for (XII) yields givenin g).
