The structure described by KAuCl4 crystallizes in the monoclinic Pc space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 9-coordinate geometry to one Cl(3), one Cl(4), one Cl(5), one Cl(6), one Cl(8), two equivalent Cl(1), and two equivalent Cl(7) atoms. In the second K site, K(2) is bonded in a 9-coordinate geometry to one Cl(3), one Cl(4), one Cl(5), one Cl(6), one Cl(7), two equivalent Cl(2), and two equivalent Cl(8) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a square co-planar geometry to one Cl(1), one Cl(2), one Cl(3), and one Cl(4) atom. In the second Au site, Au(2) is bonded in a square co-planar geometry to one Cl(5), one Cl(6), one Cl(7), and one Cl(8) atom. There are eight inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and one Au(1) atom. In the second Cl site, Cl(2) is bonded in a 3-coordinate geometry to two equivalent K(2) and one Au(1) atom. In the third Cl site, Cl(3) is bonded in a distorted trigonal planar geometry to one K(1), one K(2), and one Au(1) atom. In the fourth Cl site, Cl(4) is bonded in a distorted trigonal planar geometry to one K(1), one K(2), and one Au(1) atom. In the fifth Cl site, Cl(5) is bonded in a distorted trigonal non-coplanar geometry to one K(1), one K(2), and one Au(2) atom. In the sixth Cl site, Cl(6) is bonded in a distorted trigonal non-coplanar geometry to one K(1), one K(2), and one Au(2) atom. In the seventh Cl site, Cl(7) is bonded to one K(2), two equivalent K(1), and one Au(2) atom to form a mixture of distorted edge and corner-sharing ClK3Au tetrahedra. In the eighth Cl site, Cl(8) is bonded to one K(1), two equivalent K(2), and one Au(2) atom to form a mixture of distorted edge and corner-sharing ClK3Au tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
