Abstract
Abstract Two new Zn(II) coordination polymers (CPs), {[Zn(L)(5-nip)]2·5.5H2O}n (1) and {[Zn(L)(5-mip)]·EtOH}n (2) [L = 1,3-bis(benzimidazol-1-yl)-2-propanol, 5-H2nip = 5-nitroisophthalic acid, 5-H2mip = 5-methyisophthalic acid] were solvothermally synthesized and characterized by elemental analyses, IR spectra, thermogravimetric analyses, and single-crystal X-ray diffraction. CP 1 possesses a 1D ladder-like chain structure and further packed into 2D supramolecular architectures by π-π stacking interactions. CP 2 exhibits a 2D 63 layer, which is finally extended into 3D supramolecular network via the weak C–H⋯O hydrogen bond interactions. CP 1 and CP 2 can be used as luminescent sensors for Hg2+ and Cr2O72− ions in water.
