Materials Data on CsAuSe by Materials Project

CsAuSe crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Cs1+ is bonded in a 7-coordinate geometry to two equivalent Au1+ and five equivalent Se2- atoms. Both Cs–Au bond lengths are 3.71 Å. There are a spread of Cs–Se bond distances ranging from 3.72–3.93 Å. Au1+ is bonded in a distorted square co-planar geometry to two equivalent Cs1+ and two equivalent Se2- atoms. Both Au–Se bond lengths are 2.46 Å. Se2- is bonded to five equivalent Cs1+ and two equivalent Au1+ atoms to form a mixture of corner and edge-sharing SeCs5Au2 pentagonal bipyramids.
