Materials Data on BClF6 by Materials Project
BClF6 is beta Sn-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two BClF6 clusters. B is bonded in a tetrahedral geometry to four F atoms. There is two shorter (1.38 Å) and two longer (1.47 Å) B–F bond length. Cl is bonded in a distorted square co-planar geometry to four F atoms. There are a spread of Cl–F bond distances ranging from 1.62–2.22 Å. There are six inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Cl atom. In the second F site, F is bonded in a single-bond geometry to one Cl atom. In the third F site, F is bonded in a single-bond geometry to one B atom. In the fourth F site, F is bonded in a single-bond geometry to one B and one Cl atom. In the fifth F site, F is bonded in a single-bond geometry to one B atom. In the sixth F site, F is bonded in a single-bond geometry to one B and one Cl atom.
