Structure of DiBIS(DIETHYLDITHIOCARBAMATO) Zinc (II) mu- bis(Diethylphosphino)ethane. 2 Toluene

Abstract

Dibis(diethyldithiocarbamato)Zinc(II)mu-bis(Diethylphosphino)ethane . 2 Toluene ((et2NCSS)2Zn)2 (mu-depe).2C7H8 Mr=1114.4, monoclinic, P 21/c, a = 12. 960(1), b = 11.311(2), c = 20.129(5), beta = 96.46(1) deg, V = 2932 A3, Z = 2, D(x) = 1.254 g cu cm, lambda (MoKa) = 0.070930 A, graphite monochromator, mu = 11.89 /cu cm, F(000) = 1180, T = 298 K, final R = 0.055 (Rw = 0.072) for 2531 observed I > 3 sigma(I) 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 .
