Synthesis,Crystal Structure and Luminescent Property of a 2-D Hybrid Constructed from [Pb₂I₄] Subunits

【摘要】 A novel organic-inorganic hybrid compound, [Pb2I4(bipy)]n (bipy = 4,4′-bipyridine), was synthesized by self-assembly and its structure was determined by X-ray crystallography method. The crystal belongs to the monoclinic system, space group P21/c with a = 4.4691(9), b = 15.385(3), c = 14.136(3) , β = 93.75(3)°, V = 969.9(3) 3, Mr = 1078.16, Dc = 3.692 g/cm3, F(000) = 916, μ = 23.688 mm-1, Z = 2, the final R = 0.0395 and wR = 0.0887 for 1557 observed reflections with I > 2σ(I). The title compound presents a two-dimensional layer-like structure constructed from [PbI5N] octahedron and bis-bridging ligand 4,4′-bipyridine. The fluorescence of the title compound is also discussed in this communication.更多还原
