Gold clustering at the methylthiolate anion
Abstract
By reaction with the aurating agents [Au(PMe3)]BF4/O3SCF3 or [{(Me3P)Au}3O]BF4 in molar ratios 1 : 1, 1 : 2 or 1 : 3, sodium methylthiolate NaSMe is converted into dinuclear [Au(PMe3)(SMe)]2 1, tetranuclear [{MeS[Au(PMe3)]2}2X2](X = BF4 2a, O3SCF3 2b) and the novel trinuclear [MeS{Au(PMe3)}3][O3SCF3]2 3 complexes.
