The material described by Nd2PdSn4 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(3), two equivalent Sn(4), and four equivalent Sn(2) atoms. In the second Nd site, Nd(2) is bonded in a 14-coordinate geometry to four equivalent Pd(1), two equivalent Sn(2), two equivalent Sn(3), two equivalent Sn(4), and four equivalent Sn(1) atoms. Pd(1) is bonded in a 9-coordinate geometry to four equivalent Nd(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 Nd(1), four equivalent Nd(2), one Pd(1), and two equivalent Sn(2) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), and two equivalent Sn(1) atoms. In the third Sn site, Sn(3) is bonded in a 4-coordinate geometry to two equivalent Nd(1), two equivalent Nd(2), two equivalent Pd(1), and four equivalent Sn(4) atoms. In the fourth Sn site, Sn(4) is bonded in a 10-coordinate geometry to two equivalent Nd(1), two equivalent Nd(2), two equivalent Pd(1), and four equivalent Sn(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
