The material described by Li2CdSnS4 is Stannite-like structured and crystallizes in the orthorhombic Pmn2_1 space group. Li(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form LiS4 tetrahedra that share corners with four equivalent Li(1)S4 tetrahedra, corners with four equivalent Cd(1)S4 tetrahedra, and corners with four equivalent Sn(1)S4 tetrahedra. Cd(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form CdS4 tetrahedra that share corners with four equivalent Sn(1)S4 tetrahedra and corners with eight equivalent Li(1)S4 tetrahedra. Sn(1) is bonded to one S(1), one S(2), and two equivalent S(3) atoms to form SnS4 tetrahedra that share corners with four equivalent Cd(1)S4 tetrahedra and corners with eight equivalent Li(1)S4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Li(1), one Cd(1), and one Sn(1) atom to form corner-sharing SLi2CdSn tetrahedra. In the second S site, S(2) is bonded to two equivalent Li(1), one Cd(1), and one Sn(1) atom to form corner-sharing SLi2CdSn tetrahedra. In the third S site, S(3) is bonded to two equivalent Li(1), one Cd(1), and one Sn(1) atom to form corner-sharing SLi2CdSn tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
