The material structure described by Ni8P3 crystallizes in the trigonal R-3c space group. There are four inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted trigonal non-coplanar geometry to one Ni(4), one P(2), and two equivalent P(1) atoms. In the second Ni site, Ni(2) is bonded in a 4-coordinate geometry to one Ni(4), one P(1), one P(3), and two equivalent P(2) atoms. In the third Ni site, Ni(3) is bonded in a 4-coordinate geometry to one P(3) and three equivalent P(1) atoms. In the fourth Ni site, Ni(4) is bonded in a 11-coordinate geometry to one Ni(4), three equivalent Ni(1), three equivalent Ni(2), one P(2), and three equivalent P(1) atoms. There are three inequivalent P sites. In the first P site, P(1) is bonded in a 10-coordinate geometry to two equivalent Ni(2), two equivalent Ni(3), two equivalent Ni(4), and four equivalent Ni(1) atoms. In the second P site, P(2) is bonded in a distorted q6 geometry to one Ni(4), three equivalent Ni(1), and six equivalent Ni(2) atoms. In the third P site, P(3) is bonded in a body-centered cubic geometry to two equivalent Ni(3) and six equivalent Ni(2) atoms. is represented by the CIF file [CIF]
