RbAuCl4 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a distorted q6 geometry to four equivalent Cl(2) and six equivalent Cl(1) atoms. Au(1) is bonded in a square co-planar geometry to two equivalent Cl(1) and two equivalent Cl(2) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to three equivalent Rb(1) and one Au(1) atom to form a mixture of distorted corner and edge-sharing ClRb3Au tetrahedra. In the second Cl site, Cl(2) is bonded in a 3-coordinate geometry to two equivalent Rb(1) and one Au(1) atom.
RbAuCl4 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded in a distorted q6 geometry to four equivalent Cl(2) and six equivalent Cl(1) atoms. There are two shorter (3.56 Å) and two longer (3.62 Å) Rb(1)-Cl(2) bond lengths. There are a spread of Rb(1)-Cl(1) bond distances ranging from 3.42-3.48 Å. Au(1) is bonded in a square co-planar geometry to two equivalent Cl(1) and two equivalent Cl(2) atoms. Both Au(1)-Cl(1) bond lengths are 2.30 Å. Both Au(1)-Cl(2) bond lengths are 2.31 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to three equivalent Rb(1) and one Au(1) atom to form a mixture of distorted corner and edge-sharing ClRb3Au tetrahedra. In the second Cl site, Cl(2) is bonded in a 3-coordinate geometry to two equivalent Rb(1) and one Au(1) atom.
