RbAuBr4 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a distorted q6 geometry to four equivalent Br(2) and six equivalent Br(1) atoms. Au(1) is bonded in a square co-planar geometry to two equivalent Br(1) and two equivalent Br(2) atoms. There are two inequivalent Br sites. In the first Br site, Br(2) is bonded in a distorted T-shaped geometry to two equivalent Rb(1) and one Au(1) atom. In the second Br site, Br(1) is bonded to three equivalent Rb(1) and one Au(1) atom to form a mixture of distorted corner and edge-sharing BrRb3Au tetrahedra.
RbAuBr4 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a distorted q6 geometry to four equivalent Br(2) and six equivalent Br(1) atoms. There are two shorter (3.70 Å) and two longer (3.79 Å) Rb(1)-Br(2) bond lengths. There are a spread of Rb(1)-Br(1) bond distances ranging from 3.56-3.72 Å. Au(1) is bonded in a square co-planar geometry to two equivalent Br(1) and two equivalent Br(2) atoms. Both Au(1)-Br(1) bond lengths are 2.45 Å. Both Au(1)-Br(2) bond lengths are 2.46 Å. There are two inequivalent Br sites. In the first Br site, Br(2) is bonded in a distorted T-shaped geometry to two equivalent Rb(1) and one Au(1) atom. In the second Br site, Br(1) is bonded to three equivalent Rb(1) and one Au(1) atom to form a mixture of distorted corner and edge-sharing BrRb3Au tetrahedra.
