摘要
In this work, a new Cd（Ⅱ） dimeric compound, [Cd（Cl）2（L）（H2O）]2 （1, L = 2-（4- fluorophenyl）-lH-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） A, β = 91.392（4）°, V = 1831.2（8） A^3, Z = 2, C3sH26Cd2F2C14Cl4N8O2, Mr = 1031.27, Dc = 1.870 g/cm3, F（000） = 1016, μ（MoKα） = 1.513 mm^-1, R = 0.0532 and wR = 0.1407. Each Cd（ll） 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.
