Materials Data on Pr3Pt4 by Materials Project
Pr3Pt4 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Pr is bonded in a 9-coordinate geometry to nine Pt atoms. There are a spread of Pr–Pt bond distances ranging from 2.95–3.42 Å. There are three inequivalent Pt sites. In the first Pt site, Pt is bonded in a 6-coordinate geometry to six equivalent Pr atoms. In the second Pt site, Pt is bonded in a 10-coordinate geometry to seven equivalent Pr and three equivalent Pt atoms. There are one shorter (2.95 Å) and two longer (3.05 Å) Pt–Pt bond lengths. In the third Pt site, Pt is bonded in a 6-coordinate geometry to six equivalent Pr atoms.
