Tl2Au4S3: x = 4/3 member of the series A2 – xAuxQ. Preparation and an analysis of its gold–gold bonding
Abstract
Tl2Au4S3 was synthesized by reacting gold with reactive fluxes of Tl2S and S; its crystal structure is characterised by sheets of buckled 16-membered rings of Au and S with short Au–Au contacts between the sheets; the Au–Au bonding has been analysed through high-level band structure calculations.
