NbP2 crystallizes in the monoclinic C2/m space group. Nb(1) is bonded in a 8-coordinate geometry to three equivalent P(2) and five equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 5-coordinate geometry to five equivalent Nb(1) atoms. In the second P site, P(2) is bonded to three equivalent Nb(1) and one P(2) atom to form a mixture of distorted corner and edge-sharing PNb3P tetrahedra.
NbP2 crystallizes in the monoclinic C2/m space group. Nb(1) is bonded in a 8-coordinate geometry to three equivalent P(2) and five equivalent P(1) atoms. All Nb(1)-P(2) bond lengths are 2.59 Å. There are a spread of Nb(1)-P(1) bond distances ranging from 2.61-2.64 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 5-coordinate geometry to five equivalent Nb(1) atoms. In the second P site, P(2) is bonded to three equivalent Nb(1) and one P(2) atom to form a mixture of distorted corner and edge-sharing PNb3P tetrahedra. The P(2)-P(2) bond length is 2.19 Å.
