 Marking atoms 'S1', 'C4', 'H4' and 'C1', 'S4' as belonging to disorder
 groups '1' and '2' respectively after consulting the original publication.
 The occupancy of the hydrogen atom 'H4' was changed from '1' to '0.874' to
 match the occupancy of the atom 'C4' that it is attached to. Atom 'C1' was
 marked as having one attached hydrogen atom.
