A new binuclear 5-coordinate distorted trigonal bipyramidal Cu(I) complex with (N′1E,N′2E)-N′1,N′2-bis(phenyl(pyridin-2-yl) methylene) oxalohydrazide (H2bpoh) has been synthesized, and characterized by spectroscopic and single crystal X-ray diffraction techniques. In the complex, H2bpoh acts as a dibasic hexadentate ligand bonding with two Cu(I) each through a carbonylate-O, azomethine-N, and pyridyl-N atoms. The complex possess a CuN2OP2 core with a considerable delocalization of charge on the five-membered chelate rings which forms an unusual intra-molecular π-π stacking and CH?π interactions. The synthesized complex exhibits excellent catalytic efficiency for a click reaction at room temperature.

A graphene based composite material with γ-Fe2O 3 nanoparticles has been synthesized via a simple chemical route. The structure and composition of nanocomposite material have been characterized by TEM, Raman and XRD. The catalytic activity of the composite has been investigated for the oxidation reactions of sulfides and aromatic alcohols using water as the solvent. Sulfides and aromatic alcohols have been selectively oxidized to corresponding sulfoxides and aldehydes, respectively, with excellent yields. In addition this nanocomposite also serves as an efficient catalyst for one-pot synthesis of a series of 1,4-disubstituted-1,2,3-triazoles via click chemistry. The catalyst could be easily isolated from the final product by magnetic decantation (applying an external magnetic field) and can be reused without significant loss of catalytic activity.
