摘要:A 2D plane coordination compound [Ag2(Dpya)2.(NO32]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,Mr = 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.(NO32]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.
