The crystal structure described by NaNbIn(PO4)3 crystallizes in the trigonal R3c space group. Na(1) is bonded in a distorted hexagonal planar geometry to three equivalent O(3) and three equivalent O(4) atoms. Nb(1) is bonded to three equivalent O(2) and three equivalent O(4) atoms to form NbO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. In(1) is bonded to three equivalent O(1) and three equivalent O(3) atoms to form InO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. P(1) 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 Nb(1)O6 octahedra and corners with two equivalent In(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-33°. There are four 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(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Nb(1) and one P(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Na(1), one In(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Na(1), one Nb(1), and one P(1) atom. is represented by the CIF card [CIF]
