Materials Data on Th(GePt)2 by Materials Project

Th(PtGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Th is bonded in a 8-coordinate geometry to eight equivalent Pt and eight equivalent Ge atoms. All Th–Pt bond lengths are 3.34 Å. All Th–Ge bond lengths are 3.36 Å. Pt is bonded in a 4-coordinate geometry to four equivalent Th and four equivalent Ge atoms. All Pt–Ge bond lengths are 2.54 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Th, four equivalent Pt, and one Ge atom. The Ge–Ge bond length is 2.47 Å.

Materials Data on Th(GePt)2 by Materials Project

Th(PtGe)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Th is bonded in a 12-coordinate geometry to eight Pt and eight Ge atoms. There are four shorter (3.32 Å) and four longer (3.36 Å) Th–Pt bond lengths. There are four shorter (3.29 Å) and four longer (3.39 Å) Th–Ge bond lengths. There are two inequivalent Pt sites. In the first Pt site, Pt is bonded in a 4-coordinate geometry to four equivalent Th and four equivalent Ge atoms. All Pt–Ge bond lengths are 2.58 Å. In the second Pt site, Pt is bonded in a 9-coordinate geometry to four equivalent Th and five Ge atoms. There are one shorter (2.46 Å) and four longer (2.53 Å) Pt–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Th and four equivalent Pt atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Th and five Pt atoms.
