In this work, a new Cd(II) dimeric compound, [Cd(Cl)2(L)(H2O)]2(1, L = 2-(4-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline), has been achieved under hydrothermal conditions. The structure of compound 1 was determined by single-crystal X-ray diffraction. Compound 1 crystallizes in monoclinic, space group P21/c with a = 8.944(2), b = 18.781(5), c = 10.904(3), β = 91.392(4)°, V = 1831.2(8) 3, Z = 2, C38H26Cd2F2Cl4Cl4N8O2, Mr = 1031.27, Dc = 1.870 g/cm3, F(000) = 1016, μ(Mo Ka) = 1.513 mm-1, R = 0.0532 and w R = 0.1407. Each Cd(II) atom is in an octahedral coordination sphere, completed by two nitrogen atoms from one L ligand, two chlorine anions, and one water oxygen atom. Two chlorine anions bridge two Cd(II) atoms to give a dimer [Cd(Cl)2(L)(H2O)]2. Adjacent dimers are stacked by one type of π-π interactions among L ligands to generate a 1D supramolecular chain. Further, the 1D supramolecular chains are stacked by another type of π-π interactions among L ligands to give a 2D supramolecular layer. Finally, the luminescent property of 1 has been studied in solid state at room temperature.
