LiInS2 is Lavarevi\'{c}ite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Li(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form LiS4 tetrahedra that share corners with four equivalent Li(1)S4 tetrahedra and corners with eight equivalent In(1)S4 tetrahedra. In(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form InS4 tetrahedra that share corners with four equivalent In(1)S4 tetrahedra and corners with eight equivalent Li(1)S4 tetrahedra. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Li(1) and two equivalent In(1) atoms to form corner-sharing SLi2In2 tetrahedra. In the second S site, S(2) is bonded to two equivalent Li(1) and two equivalent In(1) atoms to form corner-sharing SLi2In2 tetrahedra.

Li(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form LiS4 tetrahedra that share corners with four equivalent Li(1)S4 tetrahedra and corners with eight equivalent In(1)S4 tetrahedra. There is one shorter (2.44 Å) and one longer (2.45 Å) Li(1)-S(1) bond length. Both Li(1)-S(2) bond lengths are 2.44 Å. In(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form InS4 tetrahedra that share corners with four equivalent In(1)S4 tetrahedra and corners with eight equivalent Li(1)S4 tetrahedra. Both In(1)-S(1) bond lengths are 2.47 Å. There is one shorter (2.47 Å) and one longer (2.48 Å) In(1)-S(2) bond length. There are two inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Li(1) and two equivalent In(1) atoms to form corner-sharing SLi2In2 tetrahedra. In the second S site, S(2) is bonded to two equivalent Li(1) and two equivalent In(1) atoms to form corner-sharing SLi2In2 tetrahedra.
