The crystal structure described by Sr(CuIn)2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 16-coordinate geometry to eight equivalent Cu(1) and eight equivalent In(1) atoms. Cu(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Cu(1), and four equivalent In(1) atoms. In(1) is bonded to four equivalent Sr(1) and four equivalent Cu(1) atoms to form a mixture of distorted corner, edge, and face-sharing InSr4Cu4 tetrahedra. is represented by the CIF file [CIF]
