CsCu2Cl3 crystallizes in the orthorhombic Cmcm space group. Cs(1) is bonded in a 8-coordinate geometry to two equivalent Cl(1) and six equivalent Cl(2) atoms. Cu(1) is bonded to two equivalent Cl(1) and two equivalent Cl(2) atoms to form a mixture of distorted corner and edge-sharing CuCl4 tetrahedra. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 6-coordinate geometry to two equivalent Cs(1) and four equivalent Cu(1) atoms. In the second Cl site, Cl(2) is bonded in a 5-coordinate geometry to three equivalent Cs(1) and two equivalent Cu(1) atoms.
