 Splitting the incorrectly concatenated values of the '_geom_hbond' loop.

 Antanas Vaitkus,
 2017-03-06

 Changing the value of the '_geom_bond_atom_site_label_2' data item from
 'H' to 'H16D' since atom 'C16B' only has three bonded atoms 'H16D',
 'H16E' and 'H16F' within the range of 0.96 \%A and the latter two bonds
 are already described in the loop.

The following automatic conversions were performed:
'_symmetry_cell_setting' value ' monoclinic' changed to 'monoclinic'
according to '/home/saulius/struct/CIF-dictionaries/cif_core.dic'
dictionary named 'cif_core.dic' version 2.4.1 from 2010-06-29.

The following automatic conversions were performed:

'_chemical_melting_point' value '437-438 K' was changed to '437.5(5)'
- the average value was taken and precision was estimated.
