“…Mostly, Schiff-base copper complexes have been intensively investigated as enzyme mimics by their dioxygen binding ability, and catalytic activity in oxidative processes. 14,15 Some acyclic Schiff base copper(II) complexes were investigated in our laboratory as superoxide dismutase and catalase mimics, promoting the dismutation of superoxide radicals (SOD activity), and the disproportionation of hydrogen peroxide (catalase activity). 16,17 Additionally, these studies revealed that they are capable of generating reactive oxygen species (ROS), in the presence of hydrogen peroxide.…”

Recebido em 5/7/10; aceito em 17/9/10; publicado na web em 25/10/10 Herein, the immobilization of some Schiff base-copper(II) complexes in smectite clays is described as a strategy for the heterogenization of homogeneous catalysts. The obtained materials were characterized by spectroscopic techniques, mostly UV/Vis, EPR, XANES and luminescence spectroscopy. SWy-2 and synthetic Laponite clays were used for the immobilization of two different complexes that have previously shown catalytic activity in the dismutation of superoxide radicals, and disproportionation of hydrogen peroxide. The obtained results indicated the occurrence of an intriguing intramolecular redox process involving copper and the imine ligand at the surface of the clays. These studies are supported by computational calculations.

Key indicators: single-crystal X-ray study; T = 296 K; mean (C-C) = 0.004 Å; disorder in main residue; R factor = 0.037; wR factor = 0.100; data-to-parameter ratio = 14.0.In the title compound, [Co(C 10 H 12 NO 2 ) 3 ]ÁH 2 O, the Co III ion is coordinated by three O atoms and three N atoms from three bidentate 2-ethoxy-6-(methyliminomethyl)phenolate ligands in a slightly distorted octahedral environment. The water molecule connects two ligands by O-HÁ Á ÁO hydrogen bonds. One terminal methyl group is disordered over two positions, with site-occupancy factors of 0.412 (15) and 0.588 (15).

“…Schiff base compounds and their metal complexes have been widely explored due to their extensive range of applications in diverse fields (Gupta et al, 2008). They are profoundly studied due to their contribution in developing complexes bearing significant biological activities as per their properties of synthetic flexibility, selectivity and sensitivity towards the central metal atom (Zoubi et al, 2013).Schiff bases having the general structure shown below played an important role in the development of coordination chemistry as they readily form stable complexes with most of the transition and non-transition metals.…”

Schiff bases are the utmost extensively used organic compounds. An outsized number of Schiff bases and their complexes have been investigated for their fascinating and imperative properties. Schiff bases are significant class of compounds in medicinal and pharmaceutical fields as they have also been shown to exhibit wide-ranging biological activities, including antifungal, antibacterial, antiproliferative, anti-inflammatory, antiviral, and antitumor properties. The imine group present in such compounds has been shown to be critical to their biological activities. Metal complexes of Schiff bases are well renowned for their stability, biological activity and prospective applications in countless fields. This short review piles up with few examples of the most propitious biological active metal complexes of schiff bases.
