Materials Data on K7(FeTe2)4 by Materials Project
Abstract
K7(FeTe2)4 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. there are four inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six Te2- atoms. There are a spread of K–Te bond distances ranging from 3.48–4.00 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six Te2- atoms. There are a spread of K–Te bond distances ranging from 3.50–3.90 Å. In the third K1+ site, K1+ is bonded in a 4-coordinate geometry to six Te2- atoms. There are a spread of K–Te bond distances ranging from 3.53–4.31 Å. In the fourth K1+ site, K1+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are a spread of K–Te bond distances ranging from 3.62–3.82 Å. There are two inequivalent Fe+2.25+ sites. In the first Fe+2.25+ site, Fe+2.25+ is bonded to four Te2- atoms to form edge-sharing FeTe4 tetrahedra. There are one shorter (2.60 Å) and three longer (2.63 Å) Fe–Te bond lengths. In the second Fe+2.25+ site, Fe+2.25+ is bonded to four Te2- atoms to form edge-sharing FeTe4 tetrahedra. There are a spread of Fe–Te bond distances ranging from 2.59–2.64 Å. There are four inequivalentmore »
