Materials Data on K2PtCl4 by Materials Project
K2PtCl4 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. K1+ is bonded in a body-centered cubic geometry to eight equivalent Cl1- atoms. All K–Cl bond lengths are 3.30 Å. Pt2+ is bonded in a square co-planar geometry to four equivalent Cl1- atoms. All Pt–Cl bond lengths are 2.33 Å. Cl1- is bonded to four equivalent K1+ and one Pt2+ atom to form a mixture of distorted edge, face, and corner-sharing ClK4Pt square pyramids.
