Materials Data on RbAuS by Materials Project

RbAuS crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Rb1+ is bonded in a 7-coordinate geometry to two equivalent Au1+ and five equivalent S2- atoms. Both Rb–Au bond lengths are 3.54 Å. There are a spread of Rb–S bond distances ranging from 3.41–3.87 Å. Au1+ is bonded in a distorted square co-planar geometry to two equivalent Rb1+ and two equivalent S2- atoms. Both Au–S bond lengths are 2.34 Å. S2- is bonded to five equivalent Rb1+ and two equivalent Au1+ atoms to form a mixture of distorted edge and corner-sharing SRb5Au2 pentagonal bipyramids.
