Preferred Abstract (Original):
Two
new neutral dimer Cadmium(II) complexes, [Cd2(dmdphphen)2X4] 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) Å, b = 10.8875(8) Å, c = 11.5730(9) Å, α = 108.323(3)º, β =
107.010(3)º, γ = 91.260(3)º V = 1147.51(15) Å3 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.
