The structure described by Li2SnSiS4 crystallizes in the tetragonal I-42m space group. Li(1) is bonded to four equivalent S(1) atoms to form distorted LiS4 trigonal pyramids that share corners with four equivalent Si(1)S4 tetrahedra and corners with four equivalent Li(1)S4 trigonal pyramids. Sn(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. Si(1) is bonded to four equivalent S(1) atoms to form SiS4 tetrahedra that share corners with eight equivalent Li(1)S4 trigonal pyramids. S(1) is bonded in a 3-coordinate geometry to two equivalent Li(1), two equivalent Sn(1), and one Si(1) atom. is represented by the CIF file [CIF]
