The material described by LaPtSi2 crystallizes in the orthorhombic Cmcm space group. La(1) is bonded in a 14-coordinate geometry to four equivalent Pt(1), four equivalent Si(1), and six equivalent Si(2) atoms. Pt(1) is bonded in a 5-coordinate geometry to four 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 4-coordinate geometry to four equivalent La(1) and four equivalent Pt(1) atoms. In the second Si site, Si(2) is bonded in a distorted single-bond geometry to six equivalent La(1), one Pt(1), and two equivalent Si(2) atoms. is represented by the CIF card [CIF]
