Synthesis and structure of a novel tetranuclear tungsten-bismuth-sulfur complex
Reaction of [PPh4](2)[WS4] with 1/3 equiv. of BiCl3 in CH2Cl2 afforded a new W/Bi/S complex [PPh4](3)[Bi(WS4)(3)] (1). The structure of the trianion of 1 represents the first example of W/Bi/S complex which contains a central Bi coordinated by six S atoms of the three [WS4](2-) moieties.
