| 摘 要： | A new luminescent Cd(Ⅱ) compound, Cd3(OABDC)2(bipy)2(H2O)2]n (1, H3OABDC = 5-oxyacetateisophthalic acid, bipy = 4,4'-bipyridine), has been prepared by the assembly of Cd(Ⅱ) salt with the mixed ligands of H3OABDC and 4,4'-bipy under hydrothermal conditions. The crystal structure is of monoclinic, space group P2/n with a = 13.6730(5), b = 10.1265(3), c = 15.9752(4) , β = 103.061(3)o, V = 2154.70(11) 3, C40H34Cd3N4O18, Mr = 1195.94, Z = 2, Dc = 1.843 g/cm3, F(000) = 1180, μ = 1.549 mm-1, the final R = 0.0409 and wR = 0.1291 for 2746 observed reflections (I > 2σ(I)). Single-crystal X-ray structural analysis reveals that compound 1 features a self-penetrating two-dimensional (2D) layered structure. According to topology analysis, this 2D framework can be characterized as a (3,4)-connected (6.72)2 (62.8)2 (73.8.102) net that has never been reported before. Finally, these 2D layers are further linked by intermolecular hydrogen bonds and π…π interactions to form a three-dimensional (3D) supramolecular framework. Moreover, Compound 1 exhibits strong blue photoluminescence at room temperature.
