Materials Data on Zn(FeS2)4 by Materials Project
Zn(FeS2)4 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Fe+2.50+ sites. In the first Fe+2.50+ site, Fe+2.50+ is bonded to six equivalent S+1.50- atoms to form FeS6 octahedra that share corners with six equivalent ZnS6 octahedra and edges with six equivalent FeS6 octahedra. The corner-sharing octahedral tilt angles are 7°. All Fe–S bond lengths are 2.33 Å. In the second Fe+2.50+ site, Fe+2.50+ is bonded to six S+1.50- atoms to form FeS6 octahedra that share edges with two equivalent ZnS6 octahedra and edges with six FeS6 octahedra. There are four shorter (2.29 Å) and two longer (2.31 Å) Fe–S bond lengths. Zn2+ is bonded to six equivalent S+1.50- atoms to form ZnS6 octahedra that share corners with six equivalent FeS6 octahedra and edges with six equivalent FeS6 octahedra. The corner-sharing octahedral tilt angles are 7°. All Zn–S bond lengths are 2.47 Å. There are two inequivalent S+1.50- sites. In the first S+1.50- site, S+1.50- is bonded in a rectangular see-saw-like geometry to three Fe+2.50+ and one Zn2+ atom. In the second S+1.50- site, S+1.50- is bonded in a distorted T-shaped geometry to three equivalent Fe+2.50+ atoms.
