We'll start bonding 6 F around Kr with single bonds and we'll be left with 38 electrons. "electron diffraction (dating from 1968) showed that the structure was approximately, but not exactly, octahedral: the experimental spectrum differed" note that diffraction does not yield spectra, but rather "diffraction patterns" or "diffractograms". The structure of xenon hexafluoride ( $\ce {XeF6}$) has always been controversial; it is a famously strong oxidising agent, so experimental studies of it have been hampered by difficulties in the isolation and storage of pure samples. Then on reaction with an equivalent amount of XeO3, A gives B.
