Reaction of the amidate ligand N-{2-[(2-pyridylmethylene)amino]phenyl}pyridine-2-carboxamide (Hcapca) with [VOCl2(thf)(2)] and MeONa in 1 : 1 : 1 molar ratio in MeCN affords the compound trans-[VOCl(capca)] 1, while reaction of 1 with NEt4NCS, MeCO2NHEt3 and imidazole yields the complexes trans-[VO(NCS)(capca)] 2, trans-[VO(Me-CO2)(capca)] 3 and trans-[VO(im)(capca)](-) 4 respectively; the X-ray crystal structure of 1 is reported; Cw EPR studies of compounds 1-3 reveal a novel phenomenon of the reduction of their A(z) components by ca. 10% compared to N-4 reference compounds.
