The complexes of Co(II), Ni(II), Cu(II), Pd(II), Cd(II) and Zn(II) with hydrazones derived from benzoic, (p) under bar-methylbenzoic or (p) under bar-nitrobenzoic acid hydrazides and pyrrole-2-carboxaldehyde have been synthesized. The complexes have been characterized by elemental analyses, molar conductance, spectral (IR and visible) and magnetic studies. All the complexes are non-electrolytes. The IR spectral data show that the ligands act as neutral or monoanionic bidentates or as monoanionic tridentates. Spectral and magnetic studies suggest octahedral structures for all Co(II) and NI(II) complexes, square-planar structures for [Cu(PBH)(2)], [Cu(PMBH)(2)].H2O and all Pd(II) complexes and a tetragonally distorted octahedral structure for [Cu(PNBH)(2)].
