General Notes



FORMU_01  There is a discrepancy between the atom counts in the                 
          _chemical_formula_sum and the formula from the _atom_site* data.      
          Atom count from _chemical_formula_sum:H15 K5 O30 Pt1 W6               
          Atom count from the _atom_site data:  K5 O30 Pt1 W6
