LaOsGe3 crystallizes in the tetragonal I4mm space group. La(1) is bonded in a 17-coordinate geometry to five equivalent Os(1), four equivalent Ge(1), and eight equivalent Ge(2) atoms. Os(1) is bonded in a 5-coordinate geometry to five equivalent La(1), one Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent La(1), one Os(1), and four equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 2-coordinate geometry to four equivalent La(1), two equivalent Os(1), and two equivalent Ge(1) atoms.
LaOsGe3 crystallizes in the tetragonal I4mm space group. La(1) is bonded in a 17-coordinate geometry to five equivalent Os(1), four equivalent Ge(1), and eight equivalent Ge(2) atoms. There is one shorter (3.46 Å) and four longer (3.54 Å) La(1)-Os(1) bond lengths. All La(1)-Ge(1) bond lengths are 3.23 Å. There are four shorter (3.29 Å) and four longer (3.47 Å) La(1)-Ge(2) bond lengths. Os(1) is bonded in a 5-coordinate geometry to five equivalent La(1), one Ge(1), and four equivalent Ge(2) atoms.
