Bowl-like tris-[(N-methyl-2-imidazoyl)]methoxy]cyclotriguaiacyclene (TMIM-CTG) (1) was synthesized and cocrystallized with ethanol, resorcinol, and phloroglucinol to afford three molecular complexes (TMIM-CTG)-(ethanol)(3) (2), (TMIM-CTG)-(resorcinol)-(CH3CN)(2) (3), and (TMIM-CTG)-(phloroglucinol)center dot(CH3CN)(2) (4), whose Structures have been determined by X-ray single crystal analysis. Except for the hydrogen bonds between imidazole of 1 and the hydroxyl group of alcohol/phenols (O-H center dot center dot center dot N), all crystals contain self-inclusion motifs with cooperative C-H center dot center dot center dot pi, interactions which can be considered as the secondary way to extend the primary hydrogen-bonded networks to (lie frameworks with higher levels. In complex 2. two adjacent TMIM-CTGs form a self-clasping dimer by an edge-to-face C-H center dot center dot center dot pi interaction between the imidazole ring and the benzene ring of CTG, which is further extended to a one-dimensional chain by the pi-pi. interactions between adjacent imidazole rings. The ethanol molecules interact with TMIM-CTGs by hydrogen bonding and fill channels within these chains. In complex 3, the self-assembly of TMIG-CTG and resorcinol Molecules by hydrogen bonding affords the Zigzag chain, which is then extended to the (4.4) sheet by the self-inclusion between TMIG-CTGs. Complex 4 contains a two-dimensional 4.8(2) hydrogen-bonding network betweenTMIG-CTG and phloroglucinol molecules, and the self-inclusion Of TMIG-CTGs extends it to,I novel three-dimensional supramolecular framework. The acetonitrile molecules in two latter Crystals arc included within the extended organic framework.
