The material structure described by Sr2In3Al crystallizes in the trigonal P3m1 space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 12-coordinate geometry to three equivalent In(1), three equivalent In(2), three equivalent In(3), and three equivalent Al(1) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to three equivalent In(1), three equivalent In(2), three equivalent In(3), and three equivalent Al(1) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 10-coordinate geometry to three equivalent Sr(1), three equivalent Sr(2), one In(2), and three equivalent Al(1) atoms. In the second In site, In(2) is bonded in a 10-coordinate geometry to three equivalent Sr(1), three equivalent Sr(2), one In(1), and three equivalent In(3) atoms. In the third In site, In(3) is bonded in a 10-coordinate geometry to three equivalent Sr(1), three equivalent Sr(2), three equivalent In(2), and one Al(1) atom. Al(1) is bonded in a 10-coordinate geometry to three equivalent Sr(1), three equivalent Sr(2), one In(3), and three equivalent In(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
