The material described by Na4P2NO16 crystallizes in the monoclinic C2/c space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(4), one O(7), and two equivalent O(5) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to one O(1), one O(3), one O(4), and one O(8) atom. P(1) is bonded to one N(1), one O(1), one O(2), and one O(3) atom to form corner-sharing PNO3 tetrahedra. N(1) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. There are eight inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to one Na(1), one P(1), and one O(7) atom. In the second O site, O(3) is bonded in a distorted water-like geometry to one Na(2) and one P(1) atom. In the third O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Na(1) and one Na(2) atom. In the fourth O site, O(5) is bonded in a bent 120 degrees geometry to two equivalent Na(1) atoms. In the fifth O site, O(6) is bonded in a single-bond geometry to one O(8) atom. In the sixth O site, O(7) is bonded in a distorted L-shaped geometry to one Na(1) and one O(2) atom. In the seventh O site, O(8) is bonded in a distorted bent 150 degrees geometry to one Na(2) and one O(6) atom. In the eighth O site, O(1) is bonded in a distorted trigonal planar geometry to one Na(1), one Na(2), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
