Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Five organic complexes are prepared by cocrystallization of tri‐[(<italic>N</italic>‐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 <bold>5</bold>. In complex <bold>1</bold>, the two dimensional networks contain 1D zigzag chains formed by hydrogen bonding and 1D chains of homo‐included CTG motifs. Complex <bold>2</bold> has 2D 4·8² hydrogen bonding networks, and the chains of homomeric inclusion extend the 2D structure to a 3D framework. Complex <bold>3 </bold>contains four‐membered rings through hydrogen bonds, and the chains of homo‐inclusion link the rings to a novel 2D network. In complex <bold>4</bold>, 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 <bold>5</bold> and hydrogen bonds solely connect two components to a chiral (6, 3) 2D network.</p> </abstract>
