K2Cu(HCl2)2 crystallizes in the tetragonal P4_2/mnm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a body-centered cubic geometry to four equivalent Cl(1) and four equivalent Cl(2) atoms. In the second K site, K(1) is bonded in a body-centered cubic geometry to four equivalent Cl(1) and four equivalent Cl(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in an octahedral geometry to two equivalent H(1), two equivalent Cl(1), and two equivalent Cl(2) atoms. In the second Cu site, Cu(1) is bonded in an octahedral geometry to two H(1,1); two equivalent Cl(1); and two equivalent Cl(2) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one Cu(1) atom. In the second H site, H(1) is bonded in a single-bond geometry to one Cu(1) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to four K(1,1) and one Cu(1) atom to form a mixture of distorted face, corner, and edge-sharing ClK4Cu square pyramids. In the second Cl site, Cl(2) is bonded to four K(1,1) and one Cu(1) atom to form a mixture of face, corner, and edge-sharing ClK4Cu square pyramids.
