摘要
Reaction of the amide ligand N-[2-(2-pyridylmethyleneamino)phenyl]pyridine-2-carboxamide (Hcapca) with VCl3 affords the compound trans-[VCl2(capca)] 1, the first example of a vanadium(III) complex containing a vanadium-deprotonated amide nitrogen bond, while reaction of bis(pentane-2,4-dionato)oxovanadium(IV) with the related ligands 1,2-bis(2-hydroxybenzamido)benzene (H-4hybeb) and 1-(2-hydroxybenzamido)-2-(2-pyridinecarboxamido)benzene (H-3hypyb) yields the complexes Na2[VIVO(hybeb)] 2 and Na[VIVO(hypyb)] 3 respectively; the X-ray crystal structures of 1 and 3 are reported.
