La3Co4Sn13 crystallizes in the cubic Pm-3n space group. La(1) is bonded in a 16-coordinate geometry to four equivalent Co(1) and twelve equivalent Sn(1) atoms. Co(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(2) is bonded in a cuboctahedral geometry to twelve equivalent Sn(1) atoms. In the second Sn site, Sn(1) is bonded in a 9-coordinate geometry to three equivalent La(1), two equivalent Co(1), one Sn(2), and three equivalent Sn(1) atoms.
