H Pt
PtH is Tungsten Carbide structured and crystallizes in the monoclinic Cm space group. Pt(1) is bonded in a 5-coordinate geometry to five equivalent H(1) atoms. There are a spread of Pt(1)-H(1) bond distances ranging from 1.84-2.26 Å. H(1) is bonded in a 5-coordinate geometry to five equivalent Pt(1) atoms.
