Crystal structure and characterization of Bis [di(N′-ethyl-N-piperazinly-carbodithioato-S,S′) Zinc(II)] complexes:: [Zn2(S2CNC4H8NC2H5)4]

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, [Zn-2(S2CNC4H8NC2H5)(4)], was determined by X-ray diffraction methods. The compound crystallizes in Monoclinic system, space group P2(1)/c, with lattice and some related parameters a=0.886(18), b=1.955(4), c= 1.196(2) nm, beta=106.03(3)degrees, V=1.991 3(7) nm(3), Z=2, M-r=888.12, D-c=1.481 g(.)cm(-3), F(000)=928, R=0.0543 and wR=0.2276. In crystal structure of the binuclear zinc complexes is built up of centro-symmetric dimeric entities. The coordination sphere of zinc(H) 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 degrees C, leaving Zn.
