NiP crystallizes in the orthorhombic Cmc2_1 space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 5-coordinate geometry to two equivalent P(2) and three equivalent P(1) atoms. In the second Ni site, Ni(2) is bonded in a 6-coordinate geometry to two equivalent P(2) and four equivalent P(1) atoms. There are two inequivalent P sites. In the first P site, P(2) is bonded in a 6-coordinate geometry to two equivalent Ni(2) and four equivalent Ni(1) atoms. In the second P site, P(1) is bonded in a 5-coordinate geometry to two equivalent Ni(2) and three equivalent Ni(1) atoms.
NiP crystallizes in the orthorhombic Cmc2_1 space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 5-coordinate geometry to two equivalent P(2) and three equivalent P(1) atoms. There is one shorter (2.26 Å) and one longer (2.27 Å) Ni(1)-P(2) bond length. There are two shorter (2.25 Å) and one longer (2.32 Å) Ni(1)-P(1) bond length. In the second Ni site, Ni(2) is bonded in a 6-coordinate geometry to two equivalent P(2) and four equivalent P(1) atoms. There is one shorter (2.27 Å) and one longer (2.29 Å) Ni(2)-P(2) bond length. All Ni(2)-P(1) bond lengths are 2.35 Å. There are two inequivalent P sites. In the first P site, P(2) is bonded in a 6-coordinate geometry to two equivalent Ni(2) and four equivalent Ni(1) atoms. In the second P site, P(1) is bonded in a 5-coordinate geometry to two equivalent Ni(2) and three equivalent Ni(1) atoms.
