Materials Data on Mn4ZnS8 by Materials Project
Mn4ZnS8 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Mn+3.50+ sites. In the first Mn+3.50+ site, Mn+3.50+ is bonded to six equivalent S2- atoms to form MnS6 octahedra that share corners with six equivalent ZnS6 octahedra and edges with six equivalent MnS6 octahedra. The corner-sharing octahedral tilt angles are 7°. All Mn–S bond lengths are 2.45 Å. In the second Mn+3.50+ site, Mn+3.50+ is bonded to six S2- atoms to form MnS6 octahedra that share edges with two equivalent ZnS6 octahedra and edges with six MnS6 octahedra. All Mn–S bond lengths are 2.36 Å. Zn2+ is bonded to six equivalent S2- atoms to form ZnS6 octahedra that share corners with six equivalent MnS6 octahedra and edges with six equivalent MnS6 octahedra. The corner-sharing octahedral tilt angles are 7°. All Zn–S bond lengths are 2.49 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a rectangular see-saw-like geometry to three Mn+3.50+ and one Zn2+ atom. In the second S2- site, S2- is bonded in a distorted T-shaped geometry to three equivalent Mn+3.50+ atoms.
