In3(PO4)2 crystallizes in the cubic I-43d space group. In(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. P(1) is bonded in a tetrahedral geometry to one O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent In(1) and one P(1) atom to form distorted corner-sharing OIn3P tetrahedra. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one In(1) and one P(1) atom.
In3(PO4)2 crystallizes in the cubic I-43d space group. In(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(1) and two equivalent O(2) atoms. Both In(1)-O(1) bond lengths are 2.47 Å. Both In(1)-O(2) bond lengths are 2.10 Å. P(1) is bonded in a tetrahedral geometry to one O(1) and three equivalent O(2) atoms. The P(1)-O(1) bond length is 1.57 Å. All P(1)-O(2) bond lengths are 1.53 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent In(1) and one P(1) atom to form distorted corner-sharing OIn3P tetrahedra. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one In(1) and one P(1) atom.
