The compound described by SrIn4 is Magnesium tetraboride-like structured and crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 14-coordinate geometry to three equivalent In(2), three equivalent In(4), four equivalent In(1), and four equivalent In(3) atoms. There are four inequivalent In sites. In the first In site, In(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1), one In(4), and three equivalent In(3) atoms. In the second In site, In(2) is bonded in a 8-coordinate geometry to three equivalent Sr(1), one In(2), one In(3), and three equivalent In(4) atoms. In the third In site, In(3) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one In(2), one In(3), and three equivalent In(1) atoms. In the fourth In site, In(4) is bonded in a 7-coordinate geometry to three equivalent Sr(1), one In(1), and three equivalent In(2) atoms. is represented by the CIF file [CIF]
