The material described by La2CoSn4 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 11-coordinate geometry to one Co(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 Co(1), two equivalent Sn(2), two equivalent Sn(3), two equivalent Sn(4), and four equivalent Sn(1) atoms. Co(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 Co(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 Co(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 Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
