Although a search for S= O&amp;BULL;&amp;BULL;&amp;BULL; C=O interactions in the CSD showed a sizable number of structures, this communication recognizes its significance for the first time in the formation of molecular assemblies. In all the crystals in the present study except the solvent-free form, the S=O bond points almost perpendicularly to the Csp2 atom of the C=O group. This was also the most frequently observed geometrical approach in CSD analysis. The solvent-free form shows dimer formation via C-H&amp;BULL;&amp;BULL;&amp;BULL; O interaction, which has longer S=O&amp;BULL;&amp;BULL;&amp;BULL; C=O contacts.</p>1 aManoj, Kochunnoonny1 aSureshan, K., M.1 aGonnade, Rajesh, G.1 aBhadbhade, Mohan, M.1 aShashidhar, M., S.  uhttps://library.ncl.res.in/content/short-so-center-dot-center-dot-center-dot-co-contacts-associate-diastereomers-246-di-o-1
