K2Os(OCl2)2 crystallizes in the tetragonal I4/mmm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a body-centered cubic geometry to eight equivalent Cl(1) atoms. In the second K site, K(1) is bonded in a body-centered cubic geometry to eight equivalent Cl(1) atoms. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a distorted octahedral geometry to two equivalent O(1) and four equivalent Cl(1) atoms. In the second Os site, Os(1) is bonded in a distorted octahedral geometry to two equivalent O(1) and four equivalent Cl(1) atoms. O(1) is bonded in a single-bond geometry to one Os(1) atom. Cl(1) is bonded to four K(1,1) and one Os(1) atom to form a mixture of corner, face, and edge-sharing ClK4Os square pyramids.
