| Abstract | Three new Coordination Polymers (CPs), namely [Co-2(dpb)(dipe)(H2O)(2)](n) (1), [Zn-2(dpb)(dipe)(H2O)(2)](n) (2) and {[Co-2(dpb)(bib)(2)(H2O)]center dot H2O}(n) (3), where H(4)dpb = 1-(3,5-dicarboxy-benzy1)-1H-pyrazole-3,5-dicarboxylic acid, dipe = (E)-1,2-di(pyridin-4-yl)ethene, bib = 1,4-di(1H-imidazol-1-yl)benzene, have been synthesized hydrothermally and characterized. Single-crystal XRD data analysis reveals that 1 and 2 are isomorphic, and possessing a (3,4,5)-connected net with a Schlafli symbol of (4.6(2))(4.6(5))(4(2).6(5).8(3)), Complex 3 presents a (4,4,4)-connected 3-nodal 3D net with {4-6(2).8(3)}{4.6(3).8(2)}{6(4).8(2)}. Also, we systematically examined the fluorescence sensing responses of 2 to small solvent molecules and metal ions. Notably, complex 2 can act as a potential promising fluorescence sensor for sensing acetone and Fe3+ ion with high selectivity and sensitivity. Meanwhile, we have investigated the magnetic behaviors of complexes 1 and 3 with dinuclear Co(II) centers, revealing antiferromagnetic behavior in 1 and 3. (C) 2017 Elsevier Ltd.
