Co3SnInS2 crystallizes in the trigonal R-3m space group. Co(1) is bonded in a distorted linear geometry to two equivalent In(1), two equivalent Sn(1), and two equivalent S(1) atoms. In(1) is bonded to six equivalent Co(1) and six equivalent S(1) atoms to form InCo6S6 cuboctahedra that share corners with six equivalent In(1)Co6S6 cuboctahedra, edges with six equivalent In(1)Co6S6 cuboctahedra, and faces with six equivalent Sn(1)Co6S2 hexagonal bipyramids. Sn(1) is bonded to six equivalent Co(1) and two equivalent S(1) atoms to form SnCo6S2 hexagonal bipyramids that share corners with six equivalent Sn(1)Co6S2 hexagonal bipyramids and faces with six equivalent In(1)Co6S6 cuboctahedra. S(1) is bonded in a 3-coordinate geometry to three equivalent Co(1), three equivalent In(1), and one Sn(1) atom.
