The crystal structure described by NiP crystallizes in the orthorhombic Cmc2_1 space group. There are four inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 5-coordinate geometry to one P(2), two equivalent P(1), and two equivalent P(4) atoms. In the second Ni site, Ni(2) is bonded in a 5-coordinate geometry to one P(1), two equivalent P(2), and two equivalent P(3) atoms. In the third Ni site, Ni(3) is bonded in a 5-coordinate geometry to two equivalent P(2) and three equivalent P(3) atoms. In the fourth Ni site, Ni(4) is bonded in a 6-coordinate geometry to two equivalent P(4) and four equivalent P(1) atoms. There are four inequivalent P sites. In the first P site, P(2) is bonded in a 5-coordinate geometry to one Ni(1), two equivalent Ni(2), and two equivalent Ni(3) atoms. In the second P site, P(3) is bonded in a 5-coordinate geometry to two equivalent Ni(2) and three equivalent Ni(3) atoms. In the third P site, P(4) is bonded in a 6-coordinate geometry to two equivalent Ni(4) and four equivalent Ni(1) atoms. In the fourth P site, P(1) is bonded in a 5-coordinate geometry to one Ni(2), two equivalent Ni(1), and two equivalent Ni(4) atoms. is represented by the CIF card [CIF]
