The crystal structure described by Sr(HgIn)2 crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded in a 8-coordinate geometry to eight equivalent Hg(1) atoms. Hg(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Hg(1), and four equivalent In(1) atoms. In(1) is bonded to four equivalent Hg(1) atoms to form a mixture of distorted corner and edge-sharing InHg4 tetrahedra. is represented by the CIF file [CIF]
