LaIrGe is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. There are three inequivalent La sites. In the first La site, La(1) is bonded to six Ir(1,1) and six Ge(1,1) atoms to form a mixture of edge and face-sharing LaGe6Ir6 cuboctahedra. In the second La site, La(1) is bonded to six Ir(1,1) and six equivalent Ge(1) atoms to form a mixture of edge and face-sharing LaGe6Ir6 cuboctahedra. In the third La site, La(1) is bonded to six equivalent Ir(1) and six equivalent Ge(1) atoms to form a mixture of edge and face-sharing LaGe6Ir6 cuboctahedra. There are three inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 9-coordinate geometry to six La(1,1) and three Ge(1,1) atoms. In the second Ir site, Ir(1) is bonded in a 9-coordinate geometry to six La(1,1) and three Ge(1,1) atoms. In the third Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six La(1,1) and three Ir(1,1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to six La(1,1) and three Ir(1,1) atoms.
LaIrGe is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. There are three inequivalent La sites. In the first La site, La(1) is bonded to six Ir(1,1) and six Ge(1,1) atoms to form a mixture of edge and face-sharing LaGe6Ir6 cuboctahedra. There are two shorter (3.12 Å) and four longer (3.37 Å) La(1)-Ir(1,1) bond lengths. There are two shorter (3.27 Å) and four longer (3.29 Å) La(1)-Ge(1,1) bond lengths. In the second La site, La(1) is bonded to six Ir(1,1) and six equivalent Ge(1) atoms to form a mixture of edge and face-sharing LaGe6Ir6 cuboctahedra. There are two shorter (3.12 Å) and four longer (3.37 Å) La(1)-Ir(1,1) bond lengths. There are two shorter (3.27 Å) and four longer (3.29 Å) La(1)-Ge(1) bond lengths.

There are three inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 9-coordinate geometry to six La(1,1) and three Ge(1,1) atoms. There are two shorter (2.45 Å) and one longer (2.46 Å) Ir(1)-Ge(1,1) bond length. In the second Ir site, Ir(1) is bonded in a 9-coordinate geometry to six La(1,1) and three Ge(1,1) atoms. All Ir(1)-La(1) bond lengths are 3.37 Å. There are two shorter (2.45 Å) and one longer (2.46 Å) Ir(1)-Ge(1,1) bond length. In the third Ir site, Ir(1) is bonded in a 9-coordinate geometry to six equivalent La(1) and three equivalent Ge(1) atoms. There are two shorter (2.45 Å) and one longer (2.46 Å) Ir(1)-Ge(1) bond length. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six La(1,1) and three Ir(1,1) atoms. Both Ge(1)-La(1) bond lengths are 3.27 Å. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to six La(1,1) and three Ir(1,1) atoms.
