Cs2PbCl6 crystallizes in the cubic Fm-3m space group. Cs(1) is bonded to twelve equivalent Cl(1) atoms to form CsCl12 cuboctahedra that share corners with twelve equivalent Cs(1)Cl12 cuboctahedra, faces with six equivalent Cs(1)Cl12 cuboctahedra, and faces with four equivalent Pb(1)Cl6 octahedra. Pb(1) is bonded to six equivalent Cl(1) atoms to form PbCl6 octahedra that share faces with eight equivalent Cs(1)Cl12 cuboctahedra. Cl(1) is bonded to four equivalent Cs(1) and one Pb(1) atom to form a mixture of distorted corner, edge, and face-sharing ClCs4Pb square pyramids.
