Na2Cu(ICl)2 crystallizes in the tetragonal P4/mmm space group. Na(1) is bonded to two equivalent I(1) and four equivalent Cl(1,2) atoms to form a mixture of edge and corner-sharing NaI2Cl4 octahedra. The corner-sharing octahedra are not tilted. Cu(1) is bonded in a square co-planar geometry to four equivalent I(1) atoms. I(1) is bonded in a square co-planar geometry to two equivalent Na(1) and two equivalent Cu(1) atoms. Cl(1,2) is bonded in a square co-planar geometry to four equivalent Na(1) atoms.
