Abstract:

DibisdiethyldithiocarbamatoZincIImu-bisDiethylphosphinoethane . 2 Toluene et2NCSS2Zn2 mu-depe.2C7H8 Mr1114.4, monoclinic, P 21c, a 12. 9601, b 11.3112, c 20.1295, beta 96.461 deg, V 2932 A3, Z 2, Dx 1.254 g cu cm, lambda MoKa 0.070930 A, graphite monochromator, mu 11.89 cu cm, F000 1180, T 298 K, final R 0.055 Rw 0.072 for 2531 observed I 3 sigmaI reflections. The molecule is positioned symmetrically about an inversion center at the cell origin, which is situated in the center of the bridging diphosphine ligand. Toluene is disordered in this structure such that the rotation between the two positions of the methyl carbon is 36 deg. The geometry about the zinc can be described as distorted trigonal bipyramid. The Zn- P distance is 2.388 A and the zinc-sulphur distances range from 2.320 to 2. 653 A .
