LaRuGe3 crystallizes in the tetragonal I4mm space group. La(1) is bonded in a 17-coordinate geometry to five equivalent Ru(1), four equivalent Ge(1), and eight equivalent Ge(2) atoms. Ru(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 Ru(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 Ru(1), and two equivalent Ge(1) atoms.
LaRuGe3 crystallizes in the tetragonal I4mm space group. La(1) is bonded in a 17-coordinate geometry to five equivalent Ru(1), four equivalent Ge(1), and eight equivalent Ge(2) atoms. There is one shorter (3.44 Å) and four longer (3.54 Å) La(1)-Ru(1) bond lengths. All La(1)-Ge(1) bond lengths are 3.22 Å. There are four shorter (3.29 Å) and four longer (3.45 Å) La(1)-Ge(2) bond lengths. Ru(1) is bonded in a 5-coordinate geometry to five equivalent La(1), one Ge(1), and four equivalent Ge(2) atoms.
