LiCeSn2 crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded in a 5-coordinate geometry to four equivalent Ce(1), one Sn(2), and four equivalent Sn(1) atoms. Ce(1) is bonded in a 14-coordinate geometry to four equivalent Li(1), four equivalent Sn(1), and six equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to four equivalent Li(1) and four equivalent Ce(1) atoms to form a mixture of distorted edge and face-sharing SnLi4Ce4 tetrahedra. In the second Sn site, Sn(2) is bonded in a distorted single-bond geometry to one Li(1) and six equivalent Ce(1) atoms.
LiCeSn2 crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded in a 5-coordinate geometry to four equivalent Ce(1), one Sn(2), and four equivalent Sn(1) atoms. All Li(1)-Ce(1) bond lengths are 3.49 Å. The Li(1)-Sn(2) bond length is 2.52 Å. There are two shorter (2.66 Å) and two longer (2.68 Å) Li(1)-Sn(1) bond lengths. Ce(1) is bonded in a 14-coordinate geometry to four equivalent Li(1), four equivalent Sn(1), and six equivalent Sn(2) atoms. There are two shorter (3.54 Å) and two longer (3.57 Å) Ce(1)-Sn(1) bond lengths. There are four shorter (3.43 Å) and two longer (3.65 Å) Ce(1)-Sn(2) bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to four equivalent Li(1) and four equivalent Ce(1) atoms to form a mixture of distorted edge and face-sharing SnLi4Ce4 tetrahedra.
