The material described by Ni3In7 crystallizes in the cubic Im-3m space group. Ni(1) is bonded in a 9-coordinate geometry to one Ni(1), four equivalent In(1), and four equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 4-coordinate geometry to four equivalent Ni(1) atoms. In the second In site, In(2) is bonded in a 7-coordinate geometry to three equivalent Ni(1) and four equivalent In(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
