Materials Data on CBr3F by Materials Project

CFBr3 is beta Np structured and crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four tribromofluoromethane molecules. C4+ is bonded in a distorted tetrahedral geometry to three Br1- and one F1- atom. There is two shorter (1.95 Å) and one longer (1.96 Å) C–Br bond length. The C–F bond length is 1.36 Å. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one C4+ atom. In the second Br1- site, Br1- is bonded in a distorted single-bond geometry to one C4+ atom. F1- is bonded in a single-bond geometry to one C4+ atom.

Materials Data on CBrF2 by Materials Project

CBrF2 is black P structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four bromodifluoromethane molecules. C3+ is bonded in a distorted water-like geometry to one Br1- and two F1- atoms. The C–Br bond length is 1.95 Å. Both C–F bond lengths are 1.36 Å. Br1- is bonded in a distorted single-bond geometry to one C3+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one C3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one C3+ atom.
