The material described by In2P6O19 crystallizes in the orthorhombic Pmmn space group. In(1) is bonded to two equivalent O(2), two equivalent O(4), and two equivalent O(6) atoms to form InO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with four equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(5), one O(7), and two equivalent O(6) atoms to form PO4 tetrahedra that share corners with two equivalent In(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. In the second P site, P(2) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with two equivalent In(1)O6 octahedra and corners with two equivalent P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 38-44°. There are seven inequivalent O sites. In the first O site, O(4) is bonded in a distorted bent 150 degrees geometry to one In(1) and one P(2) atom. In the second O site, O(5) is bonded in a single-bond geometry to one P(1) atom. In the third O site, O(6) is bonded in a distorted bent 150 degrees geometry to one In(1) and one P(1) atom. In the fourth O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent P(2) atoms. In the fifth O site, O(2) is bonded in a bent 150 degrees geometry to one In(1) and one P(2) atom. In the sixth O site, O(7) is bonded in a bent 150 degrees geometry to two equivalent P(1) atoms. In the seventh O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent P(2) atoms. is represented by the CIF card [CIF]
