La3Ru4Sn13 crystallizes in the cubic Pm-3n space group. La(1) is bonded in a 16-coordinate geometry to four equivalent Ru(1) and twelve equivalent Sn(1) atoms. Ru(1) is bonded in a 9-coordinate geometry to three equivalent La(1) and six equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 2-coordinate geometry to three equivalent La(1), two equivalent Ru(1), and one Sn(2) atom. In the second Sn site, Sn(2) is bonded in a cuboctahedral geometry to twelve equivalent Sn(1) atoms.
