The compound described by Cs2PtH4 crystallizes in the tetragonal P4_2/mnm space group. Cs(1) is bonded in a 8-coordinate geometry to four equivalent H(1) and four equivalent H(2) atoms. Pt(1) is bonded in a square co-planar geometry to two equivalent H(1) and two equivalent H(2) atoms. There are two inequivalent H sites. In the first H site, H(2) is bonded to four equivalent Cs(1) and one Pt(1) atom to form a mixture of distorted face, corner, and edge-sharing HCs4Pt square pyramids. In the second H site, H(1) is bonded to four equivalent Cs(1) and one Pt(1) atom to form a mixture of distorted face, corner, and edge-sharing HCs4Pt square pyramids. is represented by the CIF file [CIF]
