Divide by 11 if you count all atoms, including H-atoms; divide by 20-22 if
you only count non-H-atoms, to get the approximately number of atoms in
the unit cell.

Hi all,
I've had an interesting question from an undergradute student, asking if
there's any specific reference for the "18Å rule of thumb" in small
molecule crystallography for dividing the volume of a unit cell by 18 for
the approximate number of non-hydrogen atoms.
I'm afraid my google-fu has
