Materials Data on K2Te(WO)3 by Materials Project
Abstract
K2Te(WO)3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 2-coordinate geometry to three equivalent Te2- atoms. There are two shorter (3.45 Å) and one longer (3.64 Å) K–Te bond lengths. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to one Te2- and five O2- atoms. The K–Te bond length is 3.29 Å. There are a spread of K–O bond distances ranging from 2.65–3.06 Å. There are two inequivalent W2+ sites. In the first W2+ site, W2+ is bonded in a water-like geometry to two equivalent O2- atoms. Both W–O bond lengths are 1.95 Å. In the second W2+ site, W2+ is bonded in a distorted L-shaped geometry to two equivalent Te2- and two O2- atoms. There are one shorter (3.07 Å) and one longer (3.12 Å) W–Te bond lengths. There are one shorter (2.01 Å) and one longer (2.13 Å) W–O bond lengths. Te2- is bonded in a 10-coordinate geometry to four K1+, four equivalent W2+, and two equivalent O2- atoms. There are one shorter (3.46 Å) and one longer (3.83 Å) Te–O bond lengths. There aremore »
