Synthesis, Spectral Characterization on Bioactive Complexes Containing Schiff Base Ligand.

Abstract

Synthesis of metal complexes has been made possible by the Schiff base ligand (2,2'-diphenylenebis(1,2-phenylenebis(azanylylidene)) bis(methanylylidene))diphenyl. The ligand was synthesised by condensing 3-hydroxythiophene-2-carbaldehyde and benzene-1,2-diamine. UV-Visible, FT-IR, and certain physiochemical studies validated the structural and spectral features of the ligand and metals. For Schiff bases, it was found that the N and O atoms have been identified as ligand binding sites for metal ions. Evidence from molar conductance measurements suggests that the complexes are not electrolytic. TLC analysis was used to check the total responses. In addition to the tetrahedral geometry predicted by magnetic susceptibility data, electronic spectra for the [ZnC16H10O2N2S2], [SnC16H10O2N2S2], [VOC16H10O2N2S], [MgC16H10O2N2S] complexes indicated a square planar geometry, And their activity tested for using a disc diffusion technique.
