摘　　要：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.Five organic complexes are prepared by cocrystallization of tri-[（N-methyl-2-imidazoly）methoxy]cyclotriguiacylene （TMIM-CTG） with corresponding acids.
