Synthesis, Spectral Studies, NLO, and Biological Studies on Metal(II) Complexes of s-Triazine-Based Ligand

Abstract

A series of metal(II) complexes of [ML.H₂O] type [where M˭Cu(II), Ni(II), Co(II), and Zn(II); L˭2,4-bis(1-(2-hydroxyphenyl)ethylideneamino)-6-phenyl-1,3,5-triazine] have been synthesized and characterized by using analytical and spectral studies. Spectroscopy and other data show octahedral geometry for metal(II) complexes. The redox behavior of the copper(II) complex has been studied by using cyclic voltammetry. The second harmonic generation (SHG) efficiency of the ligand and metal(II) complexes has been found to be higher than that of urea and KDP. The in vitro antimicrobial activities of the compounds were tested and the results revealed that metal(II) complexes exhibit higher activity than the ligand.
