Study on Synthesis, Structure and Quantum Chemistry of HCu(trans-Hcydta)·2Bzim·1.5H2O·0.5MeOH·HClO4

The novel complex HCu(trans-Hcydta)?2Bzim?1.5H2O?0.5MeOH?HClO4 has been synthesized in aqueous solution, where Hcydta=1,2-cyclohexanediamine-tetraceticacid, Bzim=benzimidazole. The crystal structure of the copper complex has been determined by X-ray diffraction. The crystal belongs to monoclinic, with space group P2(1) /c with a=1.6360(6), b=1.3814(5), c=1.5503(5) nm, β=90.885(7)o, V=3.503(2) nm3, Z=4, Dx=1.495 g/cm3, μ(MoKa)=7.74 cm-1, F(000)=1640, R1=0.0750, wR=0.1526. The bond lengths of Cu-O are 0.2191(4), 0.1974(4), 0.1932(4) nm, respectively. The copperatom has a distorted cone. The study on the title complex has been performed, with quantum chemistry calculation by means of G98W package and taking Lanl2dz basis set.
