| Abstract: The title compound has been prepared and characterized by elemental analyses, infrared and raman spectra, and thermal analyses. The crystal structure of Bis [di(N′-ethyl-N-piperazinly-carbodithioato-S,S′) Zinc(Ⅱ)] complexes, [Zn2(S2CNC4H8NC2H5)4], was determined by X-ray diffraction methods. The compound crystallizes in Monoclinic system, space group P21/c, with lattice and some related parameters a=0.886(18), b=1.955(4), c=1.196(2) nm, β=106.03(3)°, V=1.991 3(7) nm3, Z=2, Mr=888.12, Dc=1.481 g·cm-3, F(000)=928, R=0.054 3 and wR=0.227 6. In crystal structure of the binuclear zinc complexes is built up of centro-symmetric dimeric entities. The coordination sphere of zinc(Ⅱ) ions is best described as a distorted tetragonal-pyramid. The IR spectral data are in agreement with the structural data. The thermal analytical data indicate that it decomposed completely at the temperature of 652.5 ℃, leaving Zn. CCDC: 286177. |
