  author={John Howard Burns and Paul Agron and Henri A. Levy},
  pages={1208 - 1209}
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 � (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.
