Two new neutral dimer Cadmium(II) complexes, [Cd-2(dmdphphen)(2)X-4] and where X = Cl (complex 1), Br (complex 2), and dmdphphen = 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline, were synthesized and characterized by an elemental analysis, UV-Vis, IR, TG/DTA, CV and single crystal X-ray diffraction. Complex 1 crystallizes in the triclinic system with the space group P-1 with unit cell parameters a = 10.1124(8) angstrom, b = 10.8875(8) angstrom, c = 11.5730(9) angstrom, alpha = 108.323(3)degrees, beta = 107.010(3)degrees, gamma = 91.260(3)degrees V = 1147.51(15) angstrom(3) and Z = 1. The Cd(II) ions are located in a slightly distorted square-pyramidal geometry. The complexes exhibit a quasi-reversible one electron response at -570 mV vs. Cp2Fe/Cp2Fe+, which has been assigned Cd(II)/Cd(III) couples. TG/DTA result shows that these complexes are very stable and decomposed through one step reaction. Calcination of Complex 1, revealed the formation of Cubic nanoparticle CdO. (C) 2015 Elsevier B.V.
