摘要：A 2D plane coordination compound [Ag₂（Dpya）₂.（NO₃）₂]n was synthesized and characterized by FT-IR,elemental analysis and TG analysis.The red crystal was obtained via solvent diffusion method at room temperature and is slightly soluble in organic solvents.Its structure was determined by single-crystal X-ray diffraction analysis.It crystallizes in monoclinic,space group P1 with a = 10.7995（13）,b = 7.4748（8）,c = 18.364（2） ?,β = 98.916（4）o,V = 1464.5（3） ?~3,Z = 2,C₂₆H₂₈Ag₂N₁₀O₆,M_r = 792.32,Dc = 1.302 Mg/m~3,F（000） = 792,μ（Mo Ka） = 1.356 mm^-1,R = 0.0575 and w R = 0.0826.The compound [Ag₂（Dpya）₂.（NO₃）₂]_n is a two-dimensional structure and there are two kinds of coordination configurations about the Ag atoms in the compound.The Ag（1） center is tetrahedrally coordinated with two O atoms of NO₃^-and two N atoms from the ligand Dpya.Meanwhile,the Ag（2） is five-coordinated by five O atoms from three NO₃^-anions.The Ag centers（Ag（1） and Ag（2）） connect to themselves as well as with each other by the bridging NO₃^-anions.And the coordination compound shows photoluminescence with an emission peak at 530 nm（λex = 450 nm） as the ligand Dpya.
