RbAu3Se2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Rb1+ is bonded in a distorted hexagonal planar geometry to six equivalent Se2- atoms. All Rb–Se bond lengths are 3.80 Å. Au1+ is bonded in a distorted linear geometry to two equivalent Se2- atoms. Both Au–Se bond lengths are 2.48 Å. Se2- is bonded in a 6-coordinate geometry to three equivalent Rb1+ and three equivalent Au1+ atoms.
RbAuSe 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 Se2- atoms. Both Rb–Au bond lengths are 3.57 Å. There are a spread of Rb–Se bond distances ranging from 3.51–3.90 Å. Au1+ is bonded in a distorted square co-planar geometry to two equivalent Rb1+ and two equivalent Se2- atoms. Both Au–Se bond lengths are 2.46 Å. Se2- is bonded to five equivalent Rb1+ and two equivalent Au1+ atoms to form a mixture of distorted edge and corner-sharing SeRb5Au2 pentagonal bipyramids.
