The material described by InBP2HO9NH4 crystallizes in the triclinic P-1 space group. The structure consists of two ammonium molecules inside a InBP2HO9 framework. In the InBP2HO9 framework, In(1) is bonded to one O(1), one O(4), one O(5), one O(7), one O(8), and one O(9) atom to form InO6 octahedra that share  a cornercorner with one B(1)O4 tetrahedra, corners with two equivalent P(1)O4 tetrahedra, and corners with three equivalent P(2)O4 tetrahedra. B(1) is bonded to one O(2), one O(3), one O(6), and one O(7) atom to form BO4 tetrahedra that share  a cornercorner with one In(1)O6 octahedra,  a cornercorner with one P(2)O4 tetrahedra, and corners with two equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 48°. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(3), one O(4), one O(6), and one O(8) atom to form PO4 tetrahedra that share corners with two equivalent In(1)O6 octahedra and corners with two equivalent B(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 37-55°. In the second P site, P(2) is bonded to one O(1), one O(2), one O(5), and one O(9) atom to form PO4 tetrahedra that share corners with three equivalent In(1)O6 octahedra and  a cornercorner with one B(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 35-50°. H(4) is bonded in a single-bond geometry to one O(7) atom. There are nine inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one In(1) and one P(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one B(1) and one P(2) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one B(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one In(1) and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one In(1) and one P(2) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one B(1) and one P(1) atom. In the seventh O site, O(7) is bonded in a 3-coordinate geometry to one In(1), one B(1), and one H(4) atom. In the eighth O site, O(8) is bonded in a bent 150 degrees geometry to one In(1) and one P(1) atom. In the ninth O site, O(9) is bonded in a distorted bent 120 degrees geometry to one In(1) and one P(2) atom. is represented by the CIF file [CIF]
