Abstract
The hydrothermal reaction of 1,3-dicyanobenzene, 1,10-phenanthroline (phen) and Pb(CH3COO)2 yields a new 1D coordination polymer, {Pb[C6H4(COO)2][phen]} n . The 1,3-benzenecarboxylate anion found in the final product was generated in situ during the synthesis by hydrolysis of 1,3-dicyanobenzene. X-ray diffraction shows that complex 1 crystallizes in the triclinic system, space group P 1, a = 7.5442(2) Å, b = 9.7962(3) Å, c = 13.1505(4) Å, α = 69.739(2) Å, β = 80.597(2) Å, γ = 71.377(2) Å, v = 862.48(4) Å3, Z = 2, D c = 2.124 Mg m−3. Complex 1 emits strong blue fluorescent light (λem(max) = 482.4 nm) when excited by UV light in the solid state at room temperature.
