Preparation of Multiple Cocrystals of Trithiocyanuric Acid with Some N‑Donor Compounds

Varied multicomponent molecular assemblies of trithiocyanuric acid (TCA) with N-donor compounds are prepared by varying the reaction conditions. The rational structural features, from a basic molecular recognition pattern to three-dimensional molecular assemblies, of the obtained molecular complexes are explained in detail with the help of single crystal X-ray diffraction analysis. The structural analysis highlights, within the cocrystals, TCA with multiple hydrogen bonding groups are capable of forming variable molecular patterns on its own results in varied molecular assemblies for the individual molecular ensembles with 4,4′-bipyridine (bpy), 1,2-bis-(4-pyridyl)­ethylene (bpyea), and 1,7-phenanthroline (phen).
