The material described by LaPtGe is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. La(1) is bonded to six equivalent Pt(1) and six equivalent Ge(1) atoms to form a mixture of face and edge-sharing LaGe6Pt6 cuboctahedra. There are three inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Ge(1) atoms. In the second Pt site, Pt(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Ge(1) atoms. In the third Pt site, Pt(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Pt(1) atoms. is represented by the CIF file [CIF]
