Abstract
<!?tlsb=-0.04pt>A new PbII coordination polymer, poly[0.75(aqua)[μ3-4,4'-(1H,1'H-[2,2'-biimidazole]-1,1'-diyl)dibenzoato-κ5O,O';N;O'',O''']]lead(II)] 1.25-hydrate], {[Pb(C20H12N4O4)(H2O)0.75]·1.25H2O}n or {[Pb(L)(H2O)0.75]·1.25H2O}n (1) [H2L = 4,4'-(1H,1'H-[2,2'-biimidazole]-1,1'-diyl)dibenzoic acid], was synthesized under solvothermal reaction conditions and characterized using microanalysis, IR spectroscopy and thermogravimetric analysis. Single-crystal structure analysis reveals that a two-dimensional corrugated layer structure is formed in 1 and that neighbouring layers are further extended into a three-dimensional structure by hydrogen-bonding interactions. In addition, a fluorescence sensing experiment towards Cu2+ based on the polymeric PbII complex was carried out.
