Complexes with a tridentate aroylhydrazone ligand: Microwave solid-state synthesis, crystalline architectures through supramolecular interactions and electrochemical properties

A series of complexes, [CuLCl]center dot 1.5H(2)O (1); [ML2]center dot X (X = 0, M = Cd, 2a; X= DMF, M = Hg, 2b; X = DMF, M = Ni, 2c); [Cu-2(OOCCH3)(2)L-2]center dot 2CH(3)OH (3) have been synthesized by microwave solid-state method with a tridentate aroylhydrazone ligand HL (HL = N-3-salicyloylpyridine-2-carboxamidrazone). All these compounds were characterized by element analysis, IR, X-ray diffraction and electrochemistry. Crystal analysis revealed that the coordination molecules extended to 3D supramolecular networks through plentiful H-bondings and weak molecular interactions between the ligand moieties and solvent molecules. Meanwhile, these compounds displayed diverse metal or ligand localized electrochemical properties. (C) 2013 Elsevier Ltd. All rights reserved.
