摘要：

The crystal structure of solid tribromofluoromethane, CFBr3, has been solved ab-initio from powder neutron diffraction data using direct methods. There is a single solid phase between 1.5 K and the melting point at 198.5 K. The structure is orthorhombic, space group Pnma, Z = 4, with a = 8.4931(2) angstrom, b = 9.6439(2) angstrom, and c = 6.2272(2) angstrom at 1.5 K. The crystal structure at 190 K is also reported.
