LiLaSn2 crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded in a 5-coordinate geometry to four equivalent La(1), one Sn(1), and four equivalent Sn(2) atoms. La(1) is bonded in a 14-coordinate geometry to four equivalent Li(1), four equivalent Sn(2), and six equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one Li(1) and six equivalent La(1) atoms. In the second Sn site, Sn(2) is bonded to four equivalent Li(1) and four equivalent La(1) atoms to form a mixture of distorted edge and face-sharing SnLi4La4 tetrahedra.
LiLaSn2 crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded in a 5-coordinate geometry to four equivalent La(1), one Sn(1), and four equivalent Sn(2) atoms. All Li(1)-La(1) bond lengths are 3.50 Å. The Li(1)-Sn(1) bond length is 2.56 Å. There are two shorter (2.69 Å) and two longer (2.71 Å) Li(1)-Sn(2) bond lengths. La(1) is bonded in a 14-coordinate geometry to four equivalent Li(1), four equivalent Sn(2), and six equivalent Sn(1) atoms. There are two shorter (3.58 Å) and two longer (3.62 Å) La(1)-Sn(2) bond lengths. There are four shorter (3.45 Å) and two longer (3.70 Å) La(1)-Sn(1) bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a distorted single-bond geometry to one Li(1) and six equivalent La(1) atoms. In the second Sn site, Sn(2) is bonded to four equivalent Li(1) and four equivalent La(1) atoms to form a mixture of distorted edge and face-sharing SnLi4La4 tetrahedra.
