Homomeric Inclusion and Hydrogen‐Bonding Cooperatively Directed Crystalline Assembly of a Cyclotriguaiacylene Derivative with Different Aromatic Acids

Five organic complexes are prepared by cocrystallization of tri‐(N‐methyl‐2‐imidazoly)methoxy]cyclotriguiacylene (TMIM‐CTG) with corresponding acids. While hydrogen bonds are the basic interactions in the five complexes, the homo‐included motifs with C? H···π interactions also control the molecular arrangement except for complex 5 . In complex 1 , the two dimensional networks contain 1D zigzag chains formed by hydrogen bonding and 1D chains of homo‐included CTG motifs. Complex 2 has 2D 4·8² hydrogen bonding networks, and the chains of homomeric inclusion extend the 2D structure to a 3D framework. Complex 3 contains four‐membered rings through hydrogen bonds, and the chains of homo‐inclusion link the rings to a novel 2D network. In complex 4 , hydrogen bonds construct a novel double‐layer 2D network, which is extended to a 3D framework by "hand‐shake" dimeric homomeric inclusion interactions. Interestingly, there is no homomeric inclusion phenomenon in complex 5 and hydrogen bonds solely connect two components to a chiral (6,3) 2D network.
