Mg2PN3 crystallizes in the orthorhombic Cmc2_1 space group. Mg(1) is bonded in a 5-coordinate geometry to one N(1) and four equivalent N(2) atoms. P(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing PN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent P(1) atoms to form distorted corner-sharing NMg2P2 tetrahedra. In the second N site, N(2) is bonded in a 5-coordinate geometry to four equivalent Mg(1) and one P(1) atom.
Mg2PN3 crystallizes in the orthorhombic Cmc2_1 space group. Mg(1) is bonded in a 5-coordinate geometry to one N(1) and four equivalent N(2) atoms. The Mg(1)-N(1) bond length is 2.11 Å. There are a spread of Mg(1)-N(2) bond distances ranging from 2.07-2.61 Å. P(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing PN4 tetrahedra. There is one shorter (1.68 Å) and one longer (1.69 Å) P(1)-N(1) bond length. Both P(1)-N(2) bond lengths are 1.61 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent P(1) atoms to form distorted corner-sharing NMg2P2 tetrahedra. In the second N site, N(2) is bonded in a 5-coordinate geometry to four equivalent Mg(1) and one P(1) atom.
