The material structure described by Th(PO3)4 crystallizes in the monoclinic C2/c space group. Th(1) is bonded in a 8-coordinate geometry to two equivalent O(3), two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a trigonal planar geometry to one O(1), one O(3), and one O(4) atom. In the second P site, P(2) is bonded in a trigonal planar geometry to one O(2), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(4) is bonded in a distorted linear geometry to one Th(1) and one P(1) atom. In the second O site, O(5) is bonded in a bent 150 degrees geometry to one Th(1) and one P(2) atom. In the third O site, O(6) is bonded in a bent 150 degrees geometry to one Th(1) and one P(2) atom. In the fourth O site, O(1) is bonded in a single-bond geometry to one P(1) atom. In the fifth O site, O(2) is bonded in a single-bond geometry to one P(2) atom. In the sixth O site, O(3) is bonded in a linear geometry to one Th(1) and one P(1) atom. is represented by the CIF file [CIF]
