Synthesis, Structure and Density of State of Oxalate-bridged Dinuclear Cd( Ⅱ ) Complex: [Cd2 (phen) 2ox( NO3 ) 2 (H2O) 2]
摘要
Abstract
A dinuclear Cd ( Ⅱ ) complex [Cd2 (phen)2ox( NO3 )2 (H2 O)2]was synthesized by mixing potassium oxalate ( K2ox · H2O ), cadmium nitrate [Cd ( NO3 ) 2 · 4H2O]and 1,10-phenanthroline ( phen ) in methanol-water solution. The structure was characterized by X-ray single-crystal diffraction analysis. It belongs to triclinic system, P1 space group with α =0. 67629(14) nm, b = 1. 0051 (2) nm, c = 1. 0527(2) nm, α = 109. 19(3)°, β=92. 12(3)°, γ=93.48(3)°, V=0.6733(2) nm3, Z=l, D=2.055 g/cm3, F(000) = 410,μ = 1. 660 mm-1, R =0. 0445, wR =0. 0877. The analytical results indicate that it is an oxalate-bridged dinuclear Cd( Ⅱ ) complex, the midpoint of carbon-carbon bond of oxalate is the center of inversion for the complex, Cd( Ⅱ ) cation coordinates with ox2- , phen, NO3- and H2O. The crystal field theory was used to calculate density of state(DOS) for the complex. Analysis results show that NO3- and phen have important influence on the properties of the complex.关键词
