The material described by LaPt2Si2 crystallizes in the tetragonal P4/nmm space group. La(1) is bonded in a 16-coordinate geometry to four equivalent Pt(1), four equivalent Pt(2), four equivalent Si(1), and four equivalent Si(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 4-coordinate geometry to four equivalent La(1) and four equivalent Si(2) atoms. In the second Pt site, Pt(2) 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 8-coordinate geometry to four equivalent La(1) and four equivalent Pt(2) atoms. In the second Si site, Si(2) is bonded in a 5-coordinate geometry to four equivalent La(1), one Pt(2), and four equivalent Pt(1) atoms. is represented by the CIF card [CIF]
