The material structure described by SmP3HO10NH4 crystallizes in the triclinic P-1 space group. The structure consists of two ammonium molecules inside a SmP3HO10 framework. In the SmP3HO10 framework, Sm(1) is bonded in a 8-coordinate geometry to one O(5), one O(6), one O(8), one O(9), two equivalent O(2), and two equivalent O(3) atoms. There are three 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(4) atom to form corner-sharing PO4 tetrahedra. In the second P site, P(2) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form corner-sharing PO4 tetrahedra. In the third P site, P(3) is bonded to one O(10), one O(7), one O(8), and one O(9) atom to form corner-sharing PO4 tetrahedra. H(1) is bonded in a linear geometry to one O(1) and one O(10) atom. There are ten inequivalent O sites. In the first O site, O(7) is bonded in a bent 150 degrees geometry to one P(2) and one P(3) atom. In the second O site, O(8) is bonded in a 2-coordinate geometry to one Sm(1) and one P(3) atom. In the third O site, O(9) is bonded in a 2-coordinate geometry to one Sm(1) and one P(3) atom. In the fourth O site, O(10) is bonded in a bent 120 degrees geometry to one P(3) and one H(1) atom. In the fifth O site, O(1) is bonded in a bent 120 degrees geometry to one P(1) and one H(1) atom. In the sixth O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Sm(1) and one P(1) atom. In the seventh O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Sm(1) and one P(1) atom. In the eighth O site, O(4) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the ninth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Sm(1) and one P(2) atom. In the tenth O site, O(6) is bonded in a 2-coordinate geometry to one Sm(1) and one P(2) atom. is represented by the CIF file [CIF]
