The crystal structure described by SrAuSi3 crystallizes in the tetragonal I4mm space group. Sr(1) is bonded in a 16-coordinate geometry to four equivalent Au(1), four equivalent Si(1), and eight equivalent Si(2) atoms. Au(1) is bonded in a 5-coordinate geometry to four equivalent Sr(1), one Si(1), and four equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a distorted single-bond geometry to four equivalent Sr(1) and one Au(1) atom. In the second Si site, Si(2) is bonded in a distorted bent 120 degrees geometry to four equivalent Sr(1) and two equivalent Au(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
