摘要

High-pressure X-ray investigations on crystal powders of the TiF3, titanium trifluoride, and FeF3, iron trifluoride, phases with VF3-type structures were performed up to 7.67 (7) and 9.00 (7) GPa, respectively. Both compounds are highly compressible and show strong anisotropic behavior. While the hexagonal a lattice parameters are shortened under pressure, the c parameters are elongated. These changes are associated with distortions of the TiF6 and FeF6 coordination octahedra, whereby the octahedron strain is stronger in TiF3 than in FeF3. The high-pressure behavior is characterized by cooperative tiltings of the octahedra, while simultaneously repulsive interactions between the cations probably cause the octahedral distortions.
