Abstract:
The title compound, C14H13NO5S, was synthesized via a nucleophilic substitution reaction between 3,5-di-methyl-phenol and 2-nitro-benzene-sulfonyl chloride. The aromatic rings attached to the SO3 group are oriented in a gauche fashion around the ester S-O bond, with a C-S-O-C torsion angle of 84.68 (11)°. The mol-ecules form centrosymmetric dimers via π-π stacking inter-actions between 3,5-di-methyl-phenyl groups (centroid-centroid distance = 3.709 Å). An inter-molecular S=O⋯N inter-action between the sulfonyl and nitro groups, with an O⋯N distance of 2.9840 (18) Å, organizes the dimers into columns extending along [011]. These columns are further assembled into (111) layers through C-H⋯O inter-actions.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
