Materials Data on K2Re3Se4O7 by Materials Project
Abstract
K2Re3Se4O7 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 4-coordinate geometry to one Se2- and four O2- atoms. The K–Se bond length is 3.51 Å. There are a spread of K–O bond distances ranging from 2.64–3.12 Å. In the second K1+ site, K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.70–3.39 Å. There are three inequivalent Re+6.67+ sites. In the first Re+6.67+ site, Re+6.67+ is bonded in a water-like geometry to four Se2- and two O2- atoms. There are a spread of Re–Se bond distances ranging from 2.70–2.76 Å. There is one shorter (1.75 Å) and one longer (1.76 Å) Re–O bond length. In the second Re+6.67+ site, Re+6.67+ is bonded in a distorted single-bond geometry to four Se2- and one O2- atom. There are one shorter (2.48 Å) and three longer (2.49 Å) Re–Se bond lengths. The Re–O bond length is 1.70 Å. In the third Re+6.67+ site, Re+6.67+ is bonded in a distorted single-bond geometry to four Se2- and one O2- atom. There are a spreadmore »
