| 摘 要： | The assembly of rigid 1, 4-di(1H-imidazol-4-yl)benzene (L) and Cd(OAc)2·2H2O affords an entangled complex [Cd(L)2(OAc)2]n (1) which was characterized by single-crystal X-ray diffraction, IR, elemental analysis and PXRD. The complex crystallizes in monoclinic, space group P21/c with a = 8.2603(9), b = 11.8162(13), c = 14.4138(16), β = 105.309(2)o, V = 1356.9(3)3, Z = 2, C28H26CdN8O4, Mr = 650.97, Dc = 1.593 g/cm3, μ = 0.856 mm?1, S = 1.015, F(000) = 660, the final R = 0.0456 and wR = 0.1366 for 2532 observed reflections (I > 2σ(I)). 1 possesses [Cd(L)2]n layer motifs, and parallel sets of layer motifs aggregate into a 2D + 2D → 3D mutually interpenetrated system. Photoluminescence study revealed that complex 1 exhibits strong fluorescent emission bands in the solid state at room temperature.
