摘要：

Thermal vibrational amplitudes, determined from a single-crystal X-ray study of K2TaF7 at room temperature, show similar characteristics to the neutron values for isomorphous K2NbF7, exhibiting considerable variations in anisotropies for the different fluorine atoms. These variations can be rationalized by using a combination of electron pair repulsion theory and crystal packing considerations.
