Synthesis and structural studies of some new oxovanadium [IV] complexes with ON donor schiff bases derived from 2-acetyl pyrole and o-and p-aminobenzoic acids

Coordination compounds of oxovanadium [IV] with various bases have been investigated extensively but those of the Schiff bases which are derived from heterocyclic glyoxalic aldehydes have drawn attention in recent years. In this paper we present spectroscopic and magnetic studies of new VO [IV] complexes of two ON donor Schiff bases formed by the condensation of 2-acetyl pyrrole with o- and p-aminobenzoic acids. Since the tetragonal distortion seems to be the dominant feature in the present complexes, various radial parameters have been evaluated
