The correct atom type symbol was verified by inspecting graphical image of the molecule and by matching the summary formula computed from the coordinates with the one provided by the author. Adding _cell_formula_units_Z with the value that matches the number of molecules with the number of symmetry operators, and reproduces exact summary formula as declared by the author. Saulius Gra\
