The material structure described by K3PtH5 crystallizes in the tetragonal P4/mbm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a linear geometry to two equivalent H(1) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to two equivalent H(1) and six equivalent H(2) atoms. Pt(1) is bonded in a square co-planar geometry to four equivalent H(2) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded to two equivalent K(1) and four equivalent K(2) atoms to form corner-sharing HK6 octahedra. The corner-sharing octahedral tilt angles range from 0-30°. In the second H site, H(2) is bonded in a distorted rectangular see-saw-like geometry to three equivalent K(2) and one Pt(1) atom. is represented by the CIF file [CIF]
