We have synthesized a new complex [Zn(H 2 C 3 PIm)(BTC)H 2 O] n ( 1 ) [H 3 BTC = 1,3,5‐benzenetricarboxylic acid, H 2 C 3 PIm = 2,2′‐(1,3‐propanediyl)‐bis(1H‐benzimidazole)] and determined its structure (C 26 H 20 N 4 O 7 Zn, Mr = 565.83) using single‐crystal X‐ray diffraction analysis. The complex crystallizes in the monoclinic system, space group P 2(1) with a = 8.497(5), b = 16.316(5), c = 9.316(5) Å, β = 104.955(5), V = 1247.8(11) Å 3 , Z = 2, Dc = 1.506 g · cm –3 , μ (Mo‐ K α ) = 1.038 mm –1 , F (000) = 580, S = 0.755, the final indices are R = 0.0386 and wR = 0.0456 for 3461 reflections with I > 2 σ ( I ). In the asymmetric unit of complex 1 , the distorted tetrahedral Zn II ion is bridged by the carboxylic oxygen atoms of the BTC ligand and the nitrogen atoms of the H 2 C 3 PIm ligand. The complex units are linked through BTC ligands into a chiral 2D layer and further connected into a 3D framework by π–π packing interactions between the adjacent H 2 C 3 PIm ligands. The complex exhibits high stablility in air at ambient temperature and strong photoluminescence at room temperature.
