    • Abstract

       

      Copper(II) complexes of 2-hydroxyacetophenone-N(4)-cyclohexylthiosemicarbazone (H2L1) and 2-hydroxyacetophenone-N(4)-phenylthiosemicarbazone (H2L2) have been synthesized and characterized bydifferent physicochemical techniques like magnetic studies and electronic, infrared and EPR spectral studies.[(CuL1)2] (1) is a dinuclear complex having four coordination around copper(II) with distorted square planar geometry. The two individual dinuclear complexes are interconnected through two bifurcated classical hydrogen bond interactions producing a sheet-like structure along b axis. [(CuL2)2].1/2H2O (2) also has a dimeric structure. The thiosemicarbazones bind to the metal as dianionic ONS donor ligand in all thecomplexes, except in the complexes [Cu(HL1)Cl].2H2O (3), [Cu(HL1)Br].4H2O (4) and [Cu(HL1)NO3].C2-H5OH(H2O) (5), where the ligand moieties are coordinated as monoanionic (HL¯) ones. Complexes [CuL1-dmbipy] (6), [CuL2dmbipy].3H2O (7), [CuL2bipy].H2O (8) and [CuL2phen].2C2H5OH (9) are heterocyclic base adducts.
