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 CH···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 4·8 2 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.
