Abstract
Two novel coordination polymers (CPs), namely {[Cd(TZMB)(1,4-bimb)0.5]·2.5H2O} (1) and {[Co(TZMB)(4,4′-bpy)0.5(μ2-H2O)(DMA)0.5(H2O)]·5DMA}n(2) (H2TZMB = 4,4’-(1H-1,2,4-triazol-1-yl)methylene-bis(benzonic acid), 1,4-bimb = 1,4-bis(imidazol-1-ylmethyl)benene, 4,4′-bpy = 4,4-bipyridine) have been synthesized under the solvothermal method and characterized by single-crystal X-ray diffraction analysis, IR spectra analyses (IR), elemental analyses (EA), powder X-ray diffraction (PXRD) and thermogravimetric (TG) analysis. Single X-ray diffraction analysis reveals that CPs 1 and 2 are 3D frameworks. Furthermore, luminescent measurements showed that 1 has high sensing selectivity for NACs and Fe3+ ions. In addition, the magnetic measurements indicated that 2 exhibits antiferromagnetic interactions between Co ions within the binuclear {Co2(COO)2(μ2-H2O} SBUs.
