【Abstract】 Since the first microporous zinc phosphates with zeolite-like topologies were reported by Gier and Stucky,it has attracted much attention from chemists and materials scientists due to their chemical and physical properties and the applications as catalysts,nonlinear optical materials and ion exchangers,etc.. With a view to explore a new microporous materials,an open-framework organic-inorganic hybrid zinc phosphate was synthesized by hydrothermal method when ZnCl2 and H3PO4 were chosen as raw materials,DETA as template agent. Its structure was determined by single-crystal X-ray diffraction. Crystal data:tetragonal,space group P42bc with lattice parameters a=b=1.46850(2) nm,c=0.89274(2) nm,α=β=γ=90°,V=1.92519(6) nm3,Z=8,Dc=2.641 g/cm3. The title compound was also characterized by IR spectroscopy and TG-DTA. Luminescent measurement of (C2N2H10)[Zn2(PO4)2] shows a emission band between 665 and 688 nm when excited with 451 nm UV light. The title compound may be found its applications in red lightemitting devices.更多还原
