摘要
Abstract
Two complexes,[Zn2 (pbda) 2 (H2 O) 8] · 2SO4 (1) and [Cd (pbda) 2 (H2 O) 2 (SO4)]n (2) (pbda =(E)-N1-(pyridin-4-ylmethylene) benzene-1,4-diamine) were synthesized using layer diffusion under the same condition.The complexes were characterized using IR spectra and X-ray single crystal diffraction and showed completely different fluorescent properties.Crystal structure analysis reveals that the structures of the complexes are controlled by the radii of the metal ions.Although Cd2+ ion is significantly larger than Zn2+ ion,both of the coordination numbers of metal centers in these complexes are 6,and the coordination modes and structures are completely different.The metal ion with larger radius tends to form higher dimensional structure.Different coordinated structures lead to different fluorescent emissions.关键词
