Isolation of the first gallium hydrosulphido complex and its facile conversion to a Ga4S4 cubane: X-ray structures of [(But)2Ga(µ-SH)]2 and [(ButGaS]4
Abstract
The reaction of (But)3Ga with an excess of H2S in pentane at ambient temperature results in the formation of the hydrosulphido bridged dimer [(But)2Ga(µ-SH)]2, 1, which upon mild thermolysis is converted to the cubic tetramer [(But)GaS]42. Compounds 1 and 2 have been characterized by IR, NMR and mass spectroscopy and their molecular structures have been determined by X-ray crystallography.
