Cs2Mn3S4 crystallizes in the orthorhombic Ibam space group. Cs(1) is bonded in a distorted body-centered cubic geometry to eight equivalent S(1) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to four equivalent S(1) atoms to form a mixture of edge and corner-sharing MnS4 tetrahedra. In the second Mn site, Mn(2) is bonded to four equivalent S(1) atoms to form a mixture of distorted edge and corner-sharing MnS4 tetrahedra. S(1) is bonded in a 3-coordinate geometry to four equivalent Cs(1), one Mn(1), and two equivalent Mn(2) atoms.
Cs2Mn3S4 crystallizes in the orthorhombic Ibam space group. Cs(1) is bonded in a distorted body-centered cubic geometry to eight equivalent S(1) atoms. There are a spread of Cs(1)-S(1) bond distances ranging from 3.60-3.85 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to four equivalent S(1) atoms to form a mixture of edge and corner-sharing MnS4 tetrahedra. All Mn(1)-S(1) bond lengths are 2.45 Å. In the second Mn site, Mn(2) is bonded to four equivalent S(1) atoms to form a mixture of distorted edge and corner-sharing MnS4 tetrahedra. There are two shorter (2.42 Å) and two longer (2.50 Å) Mn(2)-S(1) bond lengths. S(1) is bonded in a 3-coordinate geometry to four equivalent Cs(1), one Mn(1), and two equivalent Mn(2) atoms.
