Abstract

The compounds LiAuS and Li₃AuS₂ were synthesized by the reactions of Au and S with the Li₂S as the reactive flux. The compound LiAuS crystallizes with 16 formula units in the orthorhombic space group Fddd in a cell at T = 153 K. An earlier report of a monoclinic cell for this compound is incorrect. The compound Li₃AuS₂, which is isostructural with Na₃AuS₂, crystallizes with four formula units in the orthorhombic space group Ibam in a cell at T = 153 K. LiAuS contains infinite zigzag ¹_∞[AuS^-] chains. Li₃AuS₂ is composed of [AuS₂^3-] clusters. In both compounds, each Au atom is linearly coordinated to two atoms. Both compounds exhibit short Au^+... Au⁺ interactions: 3.1632(4) Å in LiAuS and 3.1383(6) Å in Li₃AuS₂.
