The structure described by SrLaI5 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent I(1) and six equivalent I(2) atoms. La(1) is bonded in a 8-coordinate geometry to two equivalent I(2), two equivalent I(3), and four equivalent I(1) atoms. There are three inequivalent I sites. In the first I site, I(1) is bonded in a distorted trigonal non-coplanar geometry to one Sr(1) and two equivalent La(1) atoms. In the second I site, I(2) is bonded to three equivalent Sr(1) and one La(1) atom to form a mixture of distorted corner and edge-sharing ISr3La tetrahedra. In the third I site, I(3) is bonded in a bent 150 degrees geometry to two equivalent La(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
