Materials Data on CsRe3(O3F5)2 by Materials Project
CsRe3(O3F5)2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of one CsRe3(O3F5)2 ribbon oriented in the (1, 0, 0) direction. Cs1+ is bonded in a 12-coordinate geometry to ten F1- atoms. There are a spread of Cs–F bond distances ranging from 3.14–3.36 Å. There are three inequivalent Re7+ sites. In the first Re7+ site, Re7+ is bonded to two O2- and four F1- atoms to form distorted corner-sharing ReO2F4 octahedra. The corner-sharing octahedral tilt angles are 39°. There is one shorter (1.70 Å) and one longer (1.72 Å) Re–O bond length. There are a spread of Re–F bond distances ranging from 1.88–2.26 Å. In the second Re7+ site, Re7+ is bonded to two O2- and four F1- atoms to form distorted corner-sharing ReO2F4 octahedra. The corner-sharing octahedra tilt angles range from 2–39°. There is one shorter (1.70 Å) and one longer (1.71 Å) Re–O bond length. There are a spread of Re–F bond distances ranging from 1.88–2.11 Å. In the third Re7+ site, Re7+ is bonded to two O2- and four F1- atoms to form distorted corner-sharing ReO2F4 octahedra. The corner-sharing octahedral tilt angles are 2°. There is one shorter (1.70 Å) and one longer (1.72 Å) Re–O bond length. There are a spread of Re–F bond distances ranging from 1.89–2.21 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Re7+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Re7+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one Re7+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Re7+ atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Re7+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one Re7+ atom. There are ten inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted linear geometry to two Re7+ atoms. In the second F1- site, F1- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one Re7+ atom. In the third F1- site, F1- is bonded in a distorted single-bond geometry to one Cs1+ and one Re7+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Cs1+ and one Re7+ atom. In the fifth F1- site, F1- is bonded in a distorted single-bond geometry to one Cs1+ and one Re7+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to two equivalent Cs1+ and one Re7+ atom. In the seventh F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the eighth F1- site, F1- is bonded in a 2-coordinate geometry to one Cs1+ and two Re7+ atoms. In the ninth F1- site, F1- is bonded in a single-bond geometry to one Cs1+ and one Re7+ atom. In the tenth F1- site, F1- is bonded in a single-bond geometry to one Cs1+ and one Re7+ atom.
