Dimensional effects of organic anion templates in modulating the assembly of water clusters in cucurbit[6]uril supramolecular systems
摘要:
Two new supramolecular architectures {(HC2O4)(2)(2-)[C6H18N22+ subset of C36H36N24O12]}center dot 12H(2)O (1) and {(C6H5SO3)(2)(2-)[C6H18N22+ subset of C36H36N24O12])center dot 12H(2)O (2) were synthesized and characterized by single crystal X-ray diffraction, thermogravimetric analysis and X-ray powder diffraction. Compound 1 contains infinite two dimensional (2D) L18(8)14(8)8(4) type anion-water aggregates [(HC2O4)(4) (H2O)(22)](4-) and results in the construction of sandwich-like three dimensional (3D) networks. In compound 2, honeycomb-like three dimensional (3D) networks are fabricated by one dimensional (1D) "W"-like T5(0)A2 type anion-water clusters [(C6H5SO3)(H2O)(6)](-). These results indicate that anionic groups play a crucial role in modulating the structures of water clusters with their spatial structure and binding sites. In these two structures, the majority of interactions are O center dot center dot center dot H and H center dot center dot center dot H interactions on the Hirshfeld surface, which means that hydrogen bonding and hydrophobic interactions are the dominate drive forces in forming these supramolecular systems.
