A new cadmium(II) coordination polymer constructed from 2-(2-chloro-6-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,3-benzenedicarboxylate: Synthesis, crystal structure, thermal behavior and luminescent properties

A new Cd(II) coordination polymer, nAMely, [Cd2(Cl)(1,3-BDC)1.5(L)2]·1.25H2O (1) (L = 2-(2-chloro-6-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,3-benzenedicarboxylate (1,3-BDC) was synthesized under hydrothermal conditions. The crystal of 1 belongs to orthorhombic, space group P bcn with a = 31.3116(19) Å, b = 13.5485(8) Å, c = 22.9850(15) Å, α = 90°, β = 90°, γ = 90°, C50H28.5Cd2Cl 3F 2N8O7.25, Mr = 1226.46, V = 9750.8(10) Å3, Z = 8, Dcalc = 1.671 g cm-3, S = 1.038, μ(MoKα) = 1.106 mm-1, F(000) = 4860, R = 0.0585 and wR = 0.1485. Compound 1 exhibits a 1D-ladder structure. Furthermore, neighboring 1D-ladders are joined together byπ…πinteractions to result in a 2D suprAMolecular layer. The thermal behavior of 1 was characterized. Furthermore, its luminescent properties were studied in the solid state at room temperature.
