The material described by LaRuSi2 crystallizes in the monoclinic P2_1/m space group. La(1) is bonded in a 11-coordinate geometry to two equivalent Ru(1), three equivalent Si(1), and six equivalent Si(2) atoms. Ru(1) is bonded in a 5-coordinate geometry to two equivalent La(1), one Si(2), and four equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to three equivalent La(1), four equivalent Ru(1), and two equivalent Si(1) atoms. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to six equivalent La(1), one Ru(1), and two equivalent Si(2) atoms. is represented by the CIF file [CIF]
