Crystal and molecular structure of diboron tetrafluoride, B 2F4

Abstract

X-ray diffraction study of a single crystal of B2F4 indicates a planar, centrosymmetric molecule with B-B=1.67±0.04 5 A, B-F=1.32±0.035 A and angle F-B-F=120°. There are two molecules in a monoclinic unit cell of symmetry P21/n and parameters of a=5.49, b=6.53, c=4.83, and β=102.5°.
