Abstract

A neutron-diffraction analysis of the xenon tetrafluoride crystal structure has confirmed the square-planar symmetry of the molecule; from the data the average Xe to F bond length is 1.953 Å (σ = .002) and the F to Xe to F angle is 90.0° (σ = 0.1). A description of the thermal displacements in the crystal is given.
