摘 要: | A new mononuclear Cu(Ⅱ) dithiocarbamate complex CuI(prdtc)(phen) 1 (prdtc = N-pyrrolidinyldithiocarbamate, phen = 1,10-phenanthroline) was synthesized and characterized by elemental analysis, IR spectrum, and single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/c with a = 8.7110(9), b = 14.7143(14), c = 14.8507(15) A, β = 109.721(6)°, V = 1791.9(3) A3, Z = 4, Dc = 1.916 g/cm3, CI7H16CulN3S2, Mr = 516.89, λ(MoKa) = 0.71073A,μ = 3.178 mm^-1, F(000) = 1012, the final R = 0.0369 and wR = 0.0987. A total of 4082 unique reflections were collected, of which 2916 with I 〉 2σ(I) were observed. The Cu(Ⅱ) atom is five-coordinated in a distorted square-pyramidal geometry by one I atom in the apical position, two S atoms from a prdtc ligand and two N atoms from a phen ligand in the basal plane. There exist face-to-face aromatic π-π stacking interactions between adjacent phen ligands stabilizing the structure and making the complex assemble into a 1D structure along the a axis. It can be concluded that the difference of the dtc flexibility and reaction conditions result in the structural difference between complex 1 and CuI(dmdtc)(phen) (dmdtc = N, N-dimethyldithiocarbamate).
