The structure described by Cu3Sb crystallizes in the hexagonal P-6m2 space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 6-coordinate geometry to six equivalent Cu(2) atoms. In the second Cu site, Cu(2) is bonded in a 6-coordinate geometry to three equivalent Cu(1) and three equivalent Sb(1) atoms. Sb(1) is bonded to six equivalent Cu(2) atoms to form distorted edge-sharing SbCu6 cuboctahedra. is represented by the CIF card [CIF]
