A series of new coordination complexes in volving chromium(III), manganese(III), iron(III) and cobalt(III) with Schiff bases derived from condensation of o-vanillin with diamines viz. 1,2-diaminoethane, 1,3-diaminopropane, 1,4-diaminobutane or 1,2-dia - minobenzene and monoamines viz., p-methylaniline or p-methoxyaniline have been prepared and characterized by elmental analysis, spectral (IR, electronic, 1H NMR, FAB mass), magnetic susceptibility and electrical conductance measurements. The IR spectra suggest that o-VDAEH2, o-VDAPH2, o-VDABuH2 and o-VDABH2 are dibasic tetradentate ligands to wards all the four metals giving the complexes with composition [M(L)(H2O)X] (X = Cl, and OAc; LH2 = o-VDAEH2, o-VDAPH2, o-VDABuH2 and o-VDABH2) while o-VPMEAH and o-VPMAH are monobasic bidentate ligands towards the metals giving the complexes with composition [M(Lc)3] (LcH = o-VPMEAH and o-VPMAH). Various physicochemical data suggest a six coordinated octahedral geometry for all the complexes. Studies were conducted to investigate the inhibiting potential of the complexes synthesized and the ligands, against various fungal and bacterial strains.
