Compounds <jats:bold>I<\/jats:bold> and <jats:bold>II<\/jats:bold> crystallize as discrete dimeric and tetrameric complexes, whereas <jats:bold>III<\/jats:bold>, <jats:bold>IV<\/jats:bold>, and <jats:bold>V<\/jats:bold> crystallize as polymeric two-dimensional sheets. To the best of our knowledge, compound <jats:bold>III<\/jats:bold> is the first instance of an extended hexagonal [Cu<jats:sub>3<\/jats:sub>I<jats:sub>3<\/jats:sub>] structure that is not supported by bridging ligands. Structures <jats:bold>I<\/jats:bold>, <jats:bold>II<\/jats:bold>, and <jats:bold>IV<\/jats:bold> display weak to moderately strong Cu...Cu cuprophilic interactions [Cu...Cu internuclear distances range between 2.5803\u2005(10) and 2.8485\u2005(14)\u2005\u00c5]. All structures except <jats:bold>III<\/jats:bold> display weak hydrogen-bonding interactions between the N\u2014H of the ligand and the \u03bc<jats:sub>2<\/jats:sub> and \u03bc<jats:sub>3<\/jats:sub>-I<jats:sup>\u2212<\/jats:sup> atoms. Structure <jats:bold>III<\/jats:bold> contains classical N\u2013H...O interactions between the SNO ligands that connect the molecules in a three-dimensional framework. Complex <jats:bold>V<\/jats:bold> features \u03c0\u2013\u03c0 stacking interactions between the aryl rings of the SNS6 ligands within the same polymeric sheet. In structure <jats:bold>IV<\/jats:bold>, there were three partially occupied solvent molecules of dichloromethane and one partially occupied molecule of acetonitrile present in the asymmetric unit. The SQUEEZE routine [Spek (2015). <jats:italic>Acta Cryst<\/jats:italic>. C<jats:bold>71<\/jats:bold>, 9\u201318] was used to correct the diffraction data for diffuse scattering effects and to identify the solvent molecules.
