Materials Data on BH4O2F3 by Materials Project
BH4O2F3 crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of two BH4O2F3 ribbons oriented in the (0, 0, 1) direction. B3+ is bonded in a tetrahedral geometry to one O2- and three F1- atoms. The B–O bond length is 1.53 Å. There is two shorter (1.40 Å) and one longer (1.42 Å) B–F bond length. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.65 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.63 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one B3+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to four H1+ atoms. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one B3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one B3+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one B3+ atom.
