The material structure described by LaPt2Ge2 crystallizes in the monoclinic P2_1 space group. La(1) is bonded in a 16-coordinate geometry to four equivalent Pt(1), four equivalent Pt(2), four equivalent Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 5-coordinate geometry to four equivalent La(1), one Ge(1), and four equivalent Ge(2) atoms. In the second Pt site, Pt(2) is bonded in a 4-coordinate geometry to four equivalent La(1) and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 5-coordinate geometry to four equivalent La(1), one Pt(1), and four equivalent Pt(2) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to four equivalent La(1) and four equivalent Pt(1) atoms. is represented by the CIF card [CIF]
