PN2H crystallizes in the orthorhombic P2_12_12_1 space group. 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 in a trigonal planar geometry to two equivalent P(1) and one H(1) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. H(1) is bonded in a single-bond geometry to one N(1) atom.
PN2H crystallizes in the orthorhombic P2_12_12_1 space group. P(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing PN4 tetrahedra. Both P(1)-N(1) bond lengths are 1.66 Å. Both P(1)-N(2) bond lengths are 1.59 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to two equivalent P(1) and one H(1) atom. The N(1)-H(1) bond length is 1.02 Å. In the second N site, N(2) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. H(1) is bonded in a single-bond geometry to one N(1) atom.
