Hydrothermal self-assembly of zinc nitrate with 1,1′-(1,3-propane)bis-(2-methylbenzimidazole) (pbmb) and different dicarboxylic acid ligands gave rise to three new coordination polymers [Zn(pbmb)(hmph)] n (1), {[Zn 2 (pbmb)(chdc) 2 ]⋅0.5H 2 O} n (2), [Zn(pbmb)(mip)] n (3) (H 2 hmph=homophthalic acid, H 2 chdc=1,4-cyclohexanedicarboxylic acid and H 2 mip=5-methylisophthalic acid). Both complexes 1 and 3 possess 2D {6 3 } framework and further extend into 3D supramolecular network via CH⋯O hydrogen bonding or π–π stack interactions. While 2 is a 1D double loop-like chain structure, which arranged into a 2D network through CH⋯O hydrogen bonding interactions. Three compounds all exhibit strong photoluminescence at room temperature in solid state and may be good candidates for potential luminescence materials.
