CsAuCl4 crystallizes in the monoclinic C2/c space group. Cs(1) is bonded in a 10-coordinate 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 Cs(1) and one Au(1) atom to form a mixture of distorted corner and edge-sharing ClCs3Au tetrahedra. In the second Cl site, Cl(2) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Au(1) atom.
CsAuCl4 crystallizes in the monoclinic C2/c space group. Cs(1) is bonded in a 10-coordinate geometry to four equivalent Cl(2) and six equivalent Cl(1) atoms. There are two shorter (3.74 Å) and two longer (3.82 Å) Cs(1)-Cl(2) bond lengths. There are two shorter (3.55 Å) and four longer (3.60 Å) Cs(1)-Cl(1) bond lengths. 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 2.29 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 Cs(1) and one Au(1) atom to form a mixture of distorted corner and edge-sharing ClCs3Au tetrahedra. In the second Cl site, Cl(2) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one Au(1) atom.
