Abstract

Ternary Schiff base copper(II) complex [CuL(tmpda)] (where H2L is N-(salicylidene)-L-valine; tmpda is N,N,N′,N′-tetramethyl-1,3-propanediamine) has been characterized by UV-Vis., FTIR, and single crystal XRD. The crystal structure displays a distorted square pyramidal geometry in which Schiff base is bonded to the Cu(II) ion via phenolate oxygen, imine nitrogen, and an oxygen atom of the carboxylate group through the basal plane and the chelating diamine, N,N,N′,N′-tetramethyl-1,3-propanediamine, displays an axial and equatorial mode of binding via NN-donor atoms.

Highlights

Transition metal complexes derived from Schiff bases have attracted attention of the researchers for their extensive application in the field of industry and biology [1]
The transition metal complexes derived from salicylaldehyde and amino acids can serve as nonenzymatic models for the more complicated metalpyridoxal amino acid Schiff base systems and are the key intermediates for many metabolic reactions of amino acids catalyzed by enzymes [4, 5]
Transition metal complexes derived from amino acid Schiff bases were reported to exhibit antimicrobial, antitumor, and antilarval activities and act as mimetic systems of enzyme models [6,7,8,9]

Summary

Introduction

Transition metal complexes derived from Schiff bases have attracted attention of the researchers for their extensive application in the field of industry and biology [1]. The transition metal complexes derived from salicylaldehyde and amino acids can serve as nonenzymatic models for the more complicated metalpyridoxal (vitamin B6) amino acid Schiff base systems and are the key intermediates for many metabolic reactions of amino acids catalyzed by enzymes [4, 5]. Transition metal complexes derived from amino acid Schiff bases were reported to exhibit antimicrobial, antitumor, and antilarval activities and act as mimetic systems of enzyme models [6,7,8,9]. We report the synthesis, crystal structure, and spectroscopic studies of Schiff base copper(II) complex derived from N-(salicylidene)-L-valine and, an aliphatic chelating diamine, tmpda
