Mn2SnS4 crystallizes in the orthorhombic Cmmm space group. Mn(1) is bonded to two equivalent S(2) and four equivalent S(1) atoms to form MnS6 octahedra that share corners with six equivalent Mn(1)S6 octahedra, edges with four equivalent Mn(1)S6 octahedra, and edges with four equivalent Sn(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 0-1°. Sn(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form SnS6 octahedra that share edges with two equivalent Sn(1)S6 octahedra and edges with eight equivalent Mn(1)S6 octahedra. There are two inequivalent S sites. In the first S site, S(2) is bonded in a rectangular see-saw-like geometry to two equivalent Mn(1) and two equivalent Sn(1) atoms. In the second S site, S(1) is bonded to four equivalent Mn(1) and one Sn(1) atom to form a mixture of edge and corner-sharing SMn4Sn square pyramids.
