The material structure described by Ni3ZnSb2 crystallizes in the trigonal P-3m1 space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to six equivalent Sb(1) atoms to form distorted edge-sharing NiSb6 octahedra. In the second Ni site, Ni(2) is bonded in a 7-coordinate geometry to three equivalent Zn(1) and four equivalent Sb(1) atoms. Zn(1) is bonded in a 6-coordinate geometry to six equivalent Ni(2) atoms. Sb(1) is bonded in a 7-coordinate geometry to three equivalent Ni(1) and four equivalent Ni(2) atoms. is represented by the CIF card [CIF]
