NdSn2 is Zirconium Disilicide-like structured and crystallizes in the orthorhombic Cmmm space group. Nd(1) is bonded in a 10-coordinate geometry to two equivalent Sn(1), two equivalent Sn(2), and six equivalent Sn(3) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted square co-planar geometry to four equivalent Nd(1) and four equivalent Sn(2) atoms. In the second Sn site, Sn(2) is bonded in a distorted square co-planar geometry to four equivalent Nd(1) and four equivalent Sn(1) atoms. In the third Sn site, Sn(3) is bonded in a 8-coordinate geometry to six equivalent Nd(1) and two equivalent Sn(3) atoms.
NdSn2 is Zirconium Disilicide-like structured and crystallizes in the orthorhombic Cmmm space group. Nd(1) is bonded in a 10-coordinate geometry to two equivalent Sn(1), two equivalent Sn(2), and six equivalent Sn(3) atoms. Both Nd(1)-Sn(1) bond lengths are 3.25 Å. Both Nd(1)-Sn(2) bond lengths are 3.28 Å. There are four shorter (3.29 Å) and two longer (3.58 Å) Nd(1)-Sn(3) bond lengths. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted square co-planar geometry to four equivalent Nd(1) and four equivalent Sn(2) atoms. All Sn(1)-Sn(2) bond lengths are 3.20 Å. In the second Sn site, Sn(2) is bonded in a distorted square co-planar geometry to four equivalent Nd(1) and four equivalent Sn(1) atoms. In the third Sn site, Sn(3) is bonded in a 8-coordinate geometry to six equivalent Nd(1) and two equivalent Sn(3) atoms. Both Sn(3)-Sn(3) bond lengths are 3.01 Å.
