The material structure described by Zr2Ni2Sn crystallizes in the tetragonal P4/mbm space group. Zr(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Sn(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Zr(1), one Ni(1), and two equivalent Sn(1) atoms. Sn(1) is bonded to eight equivalent Zr(1) and four equivalent Ni(1) atoms to form a mixture of corner and face-sharing SnZr8Ni4 cuboctahedra. is represented by the CIF file [CIF]
