The material structure described by SnPNO4 crystallizes in the monoclinic P2_1/c space group. Sn(1) is bonded to one N(1), one O(1), one O(2), one O(3), and one O(4) atom to form SnNO4 trigonal bipyramids that share corners with four 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 four equivalent Sn(1)NO4 trigonal bipyramids. N(1) is bonded in a bent 120 degrees geometry to one Sn(1) and one N(1) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Sn(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sn(1) and one P(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Sn(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Sn(1) and one P(1) atom. is represented by the CIF card [CIF]
