Materials Data on P2Pt5 by Materials Project
Pt5P2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Pt2- sites. In the first Pt2- site, Pt2- is bonded in a distorted water-like geometry to four equivalent Pt2- and two equivalent P5+ atoms. There are a spread of Pt–Pt bond distances ranging from 2.86–2.89 Å. There are one shorter (2.35 Å) and one longer (2.40 Å) Pt–P bond lengths. In the second Pt2- site, Pt2- is bonded in a 3-coordinate geometry to seven Pt2- and three equivalent P5+ atoms. There are a spread of Pt–Pt bond distances ranging from 2.80–2.92 Å. There are a spread of Pt–P bond distances ranging from 2.33–2.62 Å. In the third Pt2- site, Pt2- is bonded in a distorted L-shaped geometry to four equivalent Pt2- and two equivalent P5+ atoms. Both Pt–P bond lengths are 2.35 Å. P5+ is bonded in a 6-coordinate geometry to six Pt2- atoms.
