The material structure described by Mg3(Ni10P3)2 crystallizes in the cubic Fm-3m space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded to twelve equivalent Ni(2) and six equivalent P(1) atoms to form distorted MgNi12P6 cuboctahedra that share corners with twenty-four equivalent Ni(1)MgP3 tetrahedra. In the second Mg site, Mg(2) is bonded in a distorted tetrahedral geometry to four equivalent Ni(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to one Mg(2) and three equivalent P(1) atoms to form NiMgP3 tetrahedra that share corners with three equivalent Mg(1)Ni12P6 cuboctahedra, corners with six equivalent Ni(1)MgP3 tetrahedra, and edges with three equivalent Ni(1)MgP3 tetrahedra. In the second Ni site, Ni(2) is bonded in a 2-coordinate geometry to one Mg(1) and two equivalent P(1) atoms. P(1) is bonded in a 8-coordinate geometry to one Mg(1), four equivalent Ni(1), and four equivalent Ni(2) atoms. is represented by the CIF file [CIF]
