The material described by K2PtCl4 crystallizes in the tetragonal P4/mmm space group. K(1) is bonded in a body-centered cubic geometry to eight equivalent Cl(1) atoms. Pt(1) is bonded in a square co-planar geometry to four equivalent Cl(1) atoms. Cl(1) is bonded to four equivalent K(1) and one Pt(1) atom to form a mixture of corner, face, and edge-sharing ClK4Pt square pyramids. is represented by the CIF card [CIF]
