【Abstract】 A new supermolecular compound {[2-(4-chlorophenyl)benzimidazoleH]22+·[SbCl5]2-}n was synthesized by the method of hydrothermal reaction.The structure was characterized by elemental analysis,IR and fluorescence spectra.The single crystal structure was determined by X-ray single crystal diffraction.It crystallizes in monoclinic system,space group P21/c with a =0.583 0(9) nm,b=1.612 5(3) nm,c=1.616 3(3) nm,β=94.181(2)°,Z=2,V=1.515 5(4) nm3,Dc=1.662 g·cm-3,μ=1.551 mm-1,F(000)=748,R1=0.089 1,wR2=0.256 8.The single crystal structure indicates that the antimony ion and six chlorine ions form a six-coordinated distorted octahedron configuration.The 2-and 2-(4-chlorophenyl)benzimidazole cation forms the three-dimensional supermolecular of reticulation crystal by hydrogen bond,electrovalent bond and packing of aromatic ring.It has been proved that the title compound has fluorescence behaviour.更多还原
