Materials Data on H3Pt by Materials Project
PtH3 crystallizes in the hexagonal P6_3/mmc space group. The structure is two-dimensional and consists of two PtH3 sheets oriented in the (0, 0, 1) direction. Pt is bonded in a hexagonal planar geometry to six equivalent H atoms. All Pt–H bond lengths are 1.81 Å. H is bonded in a linear geometry to two equivalent Pt atoms.
