La(Ru2Sn3)2 crystallizes in the tetragonal I-42m space group. La(1) is bonded in a 16-coordinate geometry to four equivalent Ru(1), four equivalent Sn(2), and eight equivalent Sn(1) atoms. Ru(1) is bonded in a 9-coordinate geometry to one La(1), two equivalent Ru(1), two equivalent Sn(2), and four equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 5-coordinate geometry to two equivalent La(1) and four equivalent Ru(1) atoms. In the second Sn site, Sn(2) is bonded in a 4-coordinate geometry to two equivalent La(1) and four equivalent Ru(1) atoms.
La(Ru2Sn3)2 crystallizes in the tetragonal I-42m space group. La(1) is bonded in a 16-coordinate geometry to four equivalent Ru(1), four equivalent Sn(2), and eight equivalent Sn(1) atoms. All La(1)-Ru(1) bond lengths are 3.32 Å. All La(1)-Sn(2) bond lengths are 3.47 Å. There are four shorter (3.40 Å) and four longer (3.73 Å) La(1)-Sn(1) bond lengths. Ru(1) is bonded in a 9-coordinate geometry to one La(1), two equivalent Ru(1), two equivalent Sn(2), and four equivalent Sn(1) atoms. Both Ru(1)-Ru(1) bond lengths are 2.84 Å.
