The V(V) atom in the title compound, [V(C(8)H(9)N(2)O)(C(17)H(14)N(2)O(3))O]·CH(3)OH, is N,O-chelated by the benzoyl-hydrazidate anion and O,N,O'-chelated by the (benzoyl-hydrazono)propionate dianion. The octa-hedral trans-N(2)O(4) coordination geometry is completed by the vanadyl O atom. Two mononuclear complexes and two solvent mol-ecules are linked by O-H⋯O and O-H⋯N hydrogen bonds, generati...

Stepwise formation constants corresponding to 1:1 vanadyl complexes with methionine, phenyl­ alanine and threonine have been determined at 25 °C, and at various ionic concentrations, viz. 0.01, 0.1 and 0.3 M, maintained by the addition of potassium chloride solution. Thermodynamic stability constants have been obtained by extrapolation of log K values to zero ionic strength. Logarithms of the o...

Mice fed a diet low in many trace elements and raised in an environment where contamination from extraneous trace ele ments was controlled were given small amounts (5 jig/ml) of arsenite, germanate, stannous, or vanadyl ions in drinking water for their life times. Animals receiving arsenite had a significantly decreased incidence of all tumors, and of tumors of the lung, compared to those recei...

Metal based drugs have successfully been used in the detection and treatment of a variety of diseases [1]. Despite the advantages in early diagnostic and treatment of cancer, there is essential to develop new alternative of drugs. A number of in vitro studies have revealed that vanadium shows its antitumor effects on various cell lines [2]. Moreover, it is shown that vanadium compounds may show...
