A new inorganic-organic hybrid constructed from biisoquinoline dication and tin halide, [(BIQBT)(Sn Cl6)]n(1, BIQBT = 1,4-bis(isoquinoline) butane), has been synthesized and structurally determined by X-ray diffraction method. 1 crystallizes in the monoclinic system, space group Cc with Mr = 644.82, a = 16.589(3), b = 18.388(4), c = 8.5532(17), β = 108.75(3)°, V = 2470.6(9) 3, Z = 4, Dc = 1.736 g/cm3, F(000) = 1281, μ(Mo Kα) = 1.697 mm–1, the final R = 0.0197 and w R = 0.0493 for 4614 observed reflections with I 2(I). 1 consists of BIQBT2+dications and mononuclear hexachloridostannate Sn Cl62- anion, and hydrogen bonds among them contribute to the formation of a 1-D chain. Strong fluorescence can be detected in 1, which was explained by theoretical calculation. Its electrochemical behavior was investigated, and the theoretical calculations reveal that the π···π stacking interaction is dominated for their structural stabilization. 相似文献

1 INTRODUCTION Halometallates are the particularly suitable systems for designing the construction of unusual low-dimensional structural archetypes, from which peculiar electronic, thermal, catalytic and magnetic properties can arise. The syntheses of th… 相似文献
