Abstract
CrF6CrCu3(O2F)6 crystallizes in the triclinic P1 space group. The structure is three-dimensional and consists of one chromium hexafluoride molecule and one CrCu3(O2F)6 framework. In the CrCu3(O2F)6 framework, Cr is bonded to six F atoms to form CrF6 octahedra that share corners with six CuO4F2 octahedra. The corner-sharing octahedra tilt angles range from 29–47°. There are a spread of Cr–F bond distances ranging from 1.85–1.89 Å. There are three inequivalent Cu sites. In the first Cu site, Cu is bonded to four O and two F atoms to form CuO4F2 octahedra that share corners with two equivalent CrF6 octahedra. The corner-sharing octahedra tilt angles range from 36–37°. There are a spread of Cu–O bond distances ranging from 1.92–1.95 Å. Both Cu–F bond lengths are 2.22 Å. In the second Cu site, Cu is bonded to four O and two F atoms to form CuO4F2 octahedra that share corners with two equivalent CrF6 octahedra. The corner-sharing octahedra tilt angles range from 29–31°. All Cu–O bond lengths are 1.92 Å. There are one shorter (2.20 Å) and one longer (2.21 Å) Cu–F bond lengths. In the third Cu site, Cu is bonded to four O and two F atoms to form CuO4F2 octahedramore »
