Abstract :

Six co–ordinate chromium(III) complexes [CrCl(RTPP)L] (where R = H, CH3 and OCH3 group and L = 2–alkyl substituted benzimidazoles) were prepared by reacting the ligands with CrCl(RTPP). The complexes so obtained were characterized by elemental analysis, IR, U.V–visible and 1H and 13C NMR. All complexes show Cr–N stretching viations between 430–495 cm–1 and bands appeå in the range of 370–430 cm–1 shows the stretching viation for ν(Cr–Cl). The presence of axially ligated chromium(III) derivatives shows slight shift in the stretching of Cr–N in the range of 530–550 cm–1. The presence of two bands occurring between 400–610 nm confirms the, presence of Chronium(III) porphyrins with 3d3 electronic configuration of complexes. Spectral and magnetic studies suggest an octahedral geometry to these complexes. Biochemically complexes show negligible antibacterial and antioxidant behavior but well positive antifungal activity.
