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 P2(1)/c with a = 8.944(2), b = 18.781(5), c = 10.904(3) angstrom, beta = 91.392(4)degrees, V = 1831.2(8) angstrom(3), Z = 2, C38H26Cd2F2Cl4C14N8O2, M-r = 1031.27, D-c= 1.870 g/cm(3), F(000) = 1016, mu(MoKa) = 1.513 mm(-1), R = 0.0532 and wR =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 pi-pi interactions among L ligands to generate a ID supramolecular chain. Further, the ID supramolecular chains are stacked by another type of pi-pi 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.
