The compound described by La2RuSn4 crystallizes in the triclinic P1 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 11-coordinate geometry to one Ru(1), two equivalent Sn(1), two equivalent Sn(3), two equivalent Sn(4), and four equivalent Sn(2) atoms. In the second La site, La(2) is bonded in a 14-coordinate geometry to four equivalent Ru(1), two equivalent Sn(2), two equivalent Sn(3), two equivalent Sn(4), and four equivalent Sn(1) atoms. Ru(1) is bonded in a 5-coordinate geometry to one La(1), four equivalent La(2), one Sn(1), two equivalent Sn(3), and two equivalent Sn(4) atoms. There are four inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to two equivalent La(1), four equivalent La(2), one Ru(1), and two equivalent Sn(2) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to two equivalent La(2), four equivalent La(1), and two equivalent Sn(1) atoms. In the third Sn site, Sn(3) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent La(2), and two equivalent Ru(1) atoms. In the fourth Sn site, Sn(4) is bonded in a 6-coordinate geometry to two equivalent La(1), two equivalent La(2), and two equivalent Ru(1) atoms. is represented by the CIF file [CIF]
