Özet:

 

A new series of 12 complexes of oxovanadium(IV) with  hydrazones of isonicotinic acid hydrazide, namely  N-isonicotinamido-3',4',5'-trimethoxybenzalaldimine (INH-TMB) and  N-isonicotinamido-2'-furanaldimine (INH-FUR) with the general formula  VOX2.nL (X = Cl, Br, I, NCS, NO3, n = 1; X = ClO4, n = 2; L =  INH-TMB or INH-FUR) were synthesized and characterized on the basis of  analytical, conductance, molecular weight, magnetic moment, infrared  and electronic spectral data.  The infrared data of the complexes  reveal the bidendate nature of both ligands and coordination to  carbonyl-oxygen and azomethinic-nitrogen atoms.  The probable  coordination number of the central metal is 5.  Thermal stabilities of  the complexes were studied through thermogravimetric analysis.
