The material described by NaP4N7 crystallizes in the monoclinic C2/c space group. Na(1) is bonded in a 5-coordinate geometry to one N(4), two equivalent N(2), and two equivalent N(3) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one N(2), one N(4), and two equivalent N(1) atoms to form corner-sharing PN4 tetrahedra. In the second P site, P(2) is bonded to one N(1), one N(2), and two equivalent N(3) atoms to form corner-sharing PN4 tetrahedra. There are four inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one P(2) and two equivalent P(1) atoms. In the second N site, N(2) is bonded in a 3-coordinate geometry to one Na(1), one P(1), and one P(2) atom. In the third N site, N(3) is bonded in a 3-coordinate geometry to one Na(1) and two equivalent P(2) atoms. In the fourth N site, N(4) is bonded in a distorted bent 150 degrees geometry to one Na(1) and two equivalent P(1) atoms. is represented by the CIF card [CIF]
