Materials Data on FeS2 by Materials Project

Abstract

FeS2 is trigonal omega-like structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six S+1.50- atoms to form edge-sharing FeS6 octahedra. All Fe–S bond lengths are 2.27 Å. In the second Fe3+ site, Fe3+ is bonded to six S+1.50- atoms to form edge-sharing FeS6 octahedra. There are four shorter (2.27 Å) and two longer (2.28 Å) Fe–S bond lengths. In the third Fe3+ site, Fe3+ is bonded to six S+1.50- atoms to form edge-sharing FeS6 octahedra. There are four shorter (2.27 Å) and two longer (2.28 Å) Fe–S bond lengths. In the fourth Fe3+ site, Fe3+ is bonded to six S+1.50- atoms to form edge-sharing FeS6 octahedra. There are two shorter (2.27 Å) and four longer (2.28 Å) Fe–S bond lengths. There are four inequivalent S+1.50- sites. In the first S+1.50- site, S+1.50- is bonded in a distorted T-shaped geometry to three Fe3+ atoms. In the second S+1.50- site, S+1.50- is bonded in a distorted T-shaped geometry to three Fe3+ atoms. In the third S+1.50- site, S+1.50- is bonded in a distorted T-shaped geometry to three Fe3+ atoms. In the fourth S+1.50- site, S+1.50- is bonded in a distorted T-shaped geometry to three Fe3+ atoms.
