CeNiSn2 crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 14-coordinate geometry to four equivalent Ni(1), four equivalent Sn(2), and six equivalent Sn(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1), one Ni(1), and two equivalent Sn(1) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Ni(1) atoms.
CeNiSn2 crystallizes in the orthorhombic Cmcm space group. Ce(1) is bonded in a 14-coordinate geometry to four equivalent Ni(1), four equivalent Sn(2), and six equivalent Sn(1) atoms. All Ce(1)-Ni(1) bond lengths are 3.43 Å. There are two shorter (3.39 Å) and two longer (3.41 Å) Ce(1)-Sn(2) bond lengths. There are four shorter (3.38 Å) and two longer (3.64 Å) Ce(1)-Sn(1) bond lengths. Ni(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1), one Sn(1), and four equivalent Sn(2) atoms. The Ni(1)-Sn(1) bond length is 2.46 Å. All Ni(1)-Sn(2) bond lengths are 2.57 Å. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to six equivalent Ce(1), one Ni(1), and two equivalent Sn(1) atoms. Both Sn(1)-Sn(1) bond lengths are 2.83 Å. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Ce(1) and four equivalent Ni(1) atoms.
