The structure described by Nd2CoSn4 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 10-coordinate geometry to two equivalent Sn(1), two equivalent Sn(2), two equivalent Sn(3), and four equivalent Sn(4) atoms. In the second Nd site, Nd(2) is bonded in a 14-coordinate geometry to four equivalent Co(1), two equivalent Sn(1), two equivalent Sn(2), two equivalent Sn(4), and four equivalent Sn(3) atoms. Co(1) is bonded in a 5-coordinate geometry to four equivalent Nd(2), one Sn(3), two equivalent Sn(1), and two equivalent Sn(2) atoms. There are four inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 6-coordinate geometry to two equivalent Nd(1), two equivalent Nd(2), and two equivalent Co(1) atoms. In the second Sn site, Sn(2) is bonded in a 6-coordinate geometry to two equivalent Nd(1), two equivalent Nd(2), and two equivalent Co(1) atoms. In the third Sn site, Sn(3) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), one Co(1), and two equivalent Sn(4) atoms. In the fourth Sn site, Sn(4) is bonded in a 8-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), and two equivalent Sn(3) atoms. is represented by the CIF file [CIF]
