Dalton communications. Synthesis and crystal structure of [{Au2(C6H4S2-1,2)(PEt3)}2]
Abstract
Treatment of chloro(triethylphosphine)gold(I) with benzene-1,2-dithiol in the presence of a tertiary amine base affords [{Au2(C6H4S2-1,2)(PEt3)}2](60.4% Au by weight) which has a compact, centrosymmetric structure containing a rhomboid Au4 unit supported by the sulfur and phosphorus ligands.
