The material structure described by Ni21(SnP3)2 crystallizes in the cubic Fm-3m space group. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted bent 150 degrees geometry to one Ni(3) and two equivalent P(1) atoms. In the second Ni site, Ni(2) is bonded in a 4-coordinate geometry to one Sn(1) and three equivalent P(1) atoms. In the third Ni site, Ni(3) is bonded in a 18-coordinate geometry to twelve equivalent Ni(1) and six equivalent P(1) atoms. Sn(1) is bonded in a distorted tetrahedral geometry to four equivalent Ni(2) atoms. P(1) is bonded in a 8-coordinate geometry to one Ni(3), four equivalent Ni(1), and four equivalent Ni(2) atoms. is represented by the CIF card [CIF]
