Nd(PO3)3 crystallizes in the orthorhombic C222_1 space group. Nd(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(5), and four equivalent O(4) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form corner-sharing PO4 tetrahedra. In the second P site, P(2) is bonded to two equivalent O(1) and two equivalent O(4) atoms to form corner-sharing PO4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Nd(1) and one P(1) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent P(1) atoms. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Nd(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a distorted linear geometry to one Nd(1) and one P(1) atom.
Nd(PO3)3 crystallizes in the orthorhombic C222_1 space group. Nd(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(5), and four equivalent O(4) atoms. Both Nd(1)-O(2) bond lengths are 2.39 Å. Both Nd(1)-O(5) bond lengths are 2.38 Å. There are two shorter (2.44 Å) and two longer (2.68 Å) Nd(1)-O(4) bond lengths. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form corner-sharing PO4 tetrahedra. The P(1)-O(1) bond length is 1.60 Å. The P(1)-O(2) bond length is 1.48 Å.
