Abstract

The crystal and molecular structure of bis(N,N-di-n-butyldithiocarbamato)gold(III) bis(1,2-dicyanoethene-1,2-dithiolato)aurate(III), Au[S2CN(C4H9)2]2Au[S2C2(CN)2]2, has been determined from a single-crystal X-ray diffraction study. The monoclinic cell, space groupP21,/c, witha = 9·930(3),b = 12·517(3),c = 15·632(3) Å and β = 110·46(3) °, contains two formula units. Three-dimensional intensity data, up to θ = 35 ° were collected on an automatic diffractometer. Atomic parameters were refined by full-matrix least-squares methods to a conventionalR value of 0·04 for 1874 independent non-zero reflections. The structure consists of bis(di-n-butyldithiocarbamato)gold(III) cations and bis(l,2-dicyanoethene-l,2-dithiolato)aurate(III) anions. In both ions, the gold atom is in planar coordination with four sulphur atoms, the Au-S bond lengths being 2·333(4) and 2·337(4) Å in the cation and 2·312(4) and 2·306(5) Å in the anion.
