Y. Liu et al., Synthesis and crystal structure of a novel butterfly-like complex, [WOS3Cu2(PPh3)(2)(Py)(2)] (Py = pyridine), TRANSIT MET, 24(1), 1999, pp. 81-83
A new butterfly-like cluster [WOS3Cu2(PPh3)(2)(Py)(2)] was obtained by reac
ting [WOS3Cu2(PPb3)(3)] with pyridine. The crystal structure of the cluster
has been determined by X-ray diffraction. The compound shows an unusual fo
lded structure, in which two 4-coordinate Cu atoms are bound to the WOS3 mo
iety via two S-S edges.
