Materials Data on K2Cd(AuS)4 by Materials Project

Abstract

K2Cd(AuS)4 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to two equivalent Au1+ and six equivalent S2- atoms. Both K–Au bond lengths are 3.57 Å. There are a spread of K–S bond distances ranging from 3.33–3.47 Å. There are two inequivalent Au1+ sites. In the first Au1+ site, Au1+ is bonded in a 2-coordinate geometry to two equivalent K1+ and two equivalent S2- atoms. Both Au–S bond lengths are 2.34 Å. In the second Au1+ site, Au1+ is bonded in a distorted linear geometry to two equivalent S2- atoms. Both Au–S bond lengths are 2.34 Å. Cd2+ is bonded in a 4-coordinate geometry to four equivalent S2- atoms. All Cd–S bond lengths are 2.66 Å. S2- is bonded in a 6-coordinate geometry to three equivalent K1+, two Au1+, and one Cd2+ atom.
