Abstract: Three hybrids named {(tepb)[Ag4Br8]}(1), {(tepb)[Cu2(SCN)6]}(2) and {(tepb)[Ag4Br6(SCN)2]}n(3) [tepb4+ = 1, 2, 4, 5-tetrapyradyl benzene] were encountered by cation-templated self-assembly with metal thiocyanates in solution. Crystal data analysis revealed that these compounds were composed of discrete organic cations and inorganic anions by electrostatic and hydrogen bond interactions. 1 is a tetranuclear oligomer, 2 is a dimer and 3 possesses a 2D polyrotaxane layer structure. All compounds were further characterized with elemental analysis, IR spectra and thermal analysis.

Keywords: Cationic templates, supramolecular polymer, self-assembly
