Mononuclear Copper(I) Schiff Base Complex Cu((Cl-NO2-ba)2en)I(CH3CN): Synthesis and Crystal Structure

New mononuclear copper(I) Schiff base complex Cu((Cl-NO2-ba)2en)I(CH3CN) (1) containing a bidentate Schiff base ligand (Cl-NO2-ba)2en = 2,4-dichloro-5-nitro-benzylidene-1,2-diaminopropane, was prepared in an acetonitrile solution and characterized by elemental analyses (CHN), FT-IR and UV-Vis spectroscopy. Suitable dark-orange single crystals were obtained by slow evaporation of solvent at 5 ºC for several days. Crystal structure of the title compound 1 was determined by single-crystal X-ray diffraction. The complex 1 crystallizes in orthorhombic space group Pna21, a = 16.8634 (5) Å, b = 8.4460 (5) Å, c = 17.4786 (2) Å, V = 2489.45 (17) Å3 and Z = 4. In addition, the title compound 1 was used as new precursor for the synthesis of copper(II) oxide nanoparticles via solid state thermal decomposition. The as prepared CuO product was characterized by FT-IR, XRD and SEM.
