Abstract
The complexes [VX2L][L =N,N′-ethylenebis(salicylideneiminate)(salen) or N,N′-1,2-phenylenebis-(salicylideneiminate)(salphen), X = Cl or Br] have been prepared by established routes, but attempts to prepare the iodo-analogue led to other products, including [(salen)V(µ-O)VO(salen)][I5]. It is not possible to prepare hydrazine or hydrazide complexes directly from the dihalides, but [V(NH2NHPh)2(salen)]I was synthesised by an indirect route, and its structure determined by X-ray analysis. The phenylhydrazines are bound end-on. Several other new vanadium-(III) and (IV) species are described.
