  • Although we use the structure found by (Chao, 1971), we should note that there is some disagreement between the Chao's X-ray diffraction data and the neutron diffraction data taken by (Prince, 1971): while both agree on the positions of the heavy atoms, Prince's work suggests that some of the hydrogens may form OH radicals rather than water molecules.
  • In any case, the fluorine set atoms are usually partially replaced by OH radicals. This sample, which is predominantly fluorine, is technically labeled apophyllite-(KF).
