  1. Deleting two atoms:

  O10B* O -0.0364(5) 0.1450(4) -0.0652(3)
  Zn1B Zn 0.6017(1) 0.2354(1) 0.0930(1)

  These atoms seem to be symmetry-equivalent of their counterparts O10
  and Zn1, and therefore should not be present in the asymmetric-unit
  representation. With this deletion, the heavy-atom summary formula
  coincides with the formula declared by the authors.

  2. Adding the _atom_site_attached_hydrogens and the
  _atom_site_calc_flags data items. Using _atom_site_calc_flags to
  specify hudrogens attached to the dabconium moiety (14 hydrogen
  atoms), and also introducing a dummy site with the rest 5 H atoms;
  these 5 hydrogens are probably connected to the phosphates, but we
  do not know which, so I prefer to add a dummy site in order not to
  overinterpret the published data. With these additions, the computed
  summary formula is the same as declared by the authors (if the
  computing software correctly processes dummy sites and correctly
  counts all attached hydrogens).

  3. Updated bibliographic record. The journal CODEN code was looked
  up in the CASSI (Chemical Abstracts Service Source Index),
  http://cassi.cas.org/. The journal name and ISSN was checked at
  http://journalseek.net/cgi-bin/journalseek/journalsearch.cgi?field=issn&query=0992-4361.

  Changing number of hydrogens attached to phosphate oxygens from "0"
  to "?", since we do not really know which site is protonated.

The following automatic conversions were performed:
'_atom_site_calc_flags' tag replaced with '_atom_site_calc_flag'.
