Mechanochemical Synthesis of a Cocrystal of Two Supramolecular Hydrogen-Bonded Aggregates of 1,3,6,8-Tetraazatricyclo[4.3.1.13,8]undecane (TATU) with 4-tert-Butylphenol Bearing Different Hydrogen Bonding Interactions

The synthesis and single crystal structure of a new cocrystal, which is composed of OHphenolic center dot center dot center dot OHphenolic center dot center dot center dot Naminalic supramolecular heterosynthons assembled from 4-tert-butylphenol and the macrocyclic aminal TATU, is presented. This cocrystal was prepared by solvent-free assisted grinding, which is a commonly used mechanochemical method. Crystal structure, supramolecular assembly through hydrogen bonding interactions as well as the physical and spectroscopic properties of the title cocrystal are presented in this paper.
