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.
