The compound described by SrIn5 crystallizes in the hexagonal P6/mmm space group. Sr(1) is bonded in a hexagonal planar geometry to six equivalent In(2) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded to four equivalent In(1) and four equivalent In(2) atoms to form a mixture of distorted corner, edge, and face-sharing InIn8 cuboctahedra. In the second In site, In(2) is bonded in a 9-coordinate geometry to three equivalent Sr(1) and six equivalent In(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
