Materials Data on Th3Pt5 by Materials Project
Th3Pt5 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Th is bonded in a 12-coordinate geometry to six Pt atoms. There are two shorter (2.82 Å) and four longer (3.01 Å) Th–Pt bond lengths. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a trigonal planar geometry to three equivalent Th atoms. In the second Pt site, Pt is bonded in a 10-coordinate geometry to four equivalent Th atoms.
