The material structure described by Ni2SiZn3 crystallizes in the cubic Fd-3m space group. Ni(1) is bonded in a 12-coordinate geometry to three equivalent Ni(1), six equivalent Zn(1), and three equivalent Si(1) atoms. Zn(1) is bonded in a 14-coordinate geometry to four equivalent Ni(1), eight equivalent Zn(1), and two equivalent Si(1) atoms. Si(1) is bonded to six equivalent Ni(1) and six equivalent Zn(1) atoms to form face-sharing SiZn6Ni6 cuboctahedra. is represented by the CIF card [CIF]
