The compound described by Th7Pt3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Th sites. In the first Th site, Th(1) is bonded in a distorted L-shaped geometry to two equivalent Pt(1) atoms. In the second Th site, Th(2) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. In the third Th site, Th(3) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. Pt(1) is bonded in a 6-coordinate geometry to one Th(3), two equivalent Th(1), and three equivalent Th(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
