K2PtH4 crystallizes in the tetragonal I4/mmm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a distorted body-centered cubic geometry to eight equivalent H(1) atoms. In the second K site, K(1) is bonded in a distorted body-centered cubic geometry to eight equivalent H(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a square co-planar geometry to four equivalent H(1) atoms. In the second Pt site, Pt(1) is bonded in a square co-planar geometry to four equivalent H(1) atoms. H(1) is bonded to four K(1,1) and one Pt(1) atom to form a mixture of face, corner, and edge-sharing HK4Pt square pyramids.
