Synthesis, Crystal Structure and Luminescent Properties of a 1D Loop-chain Coordination Polymer Ag(3,3-pybz)(3,3-Hpybz) n

摘要

A new coordination polymer,[Ag(3,3-pybz)(3,3-Hpybz)]n(1,3,3-Hpybz=3-pyridin-3-yl-benzoic acid),has been synthesized and characterized by elemental analysis,IR spectra,PXRD,and single-crystal X-ray diffraction.In complex 1,the Ag(I)ions are linked by the paired3,3-pybz ligands to generate an infinite 1D loop chain,and further throughπ-πstacking interactions to form a 2D supramolecular architecture.Crystal data for 1:triclinic,space group P1,a=10.2635(17),b=10.3041(12),c=10.8060(13),V=1679.1(5)3,α=62.028(11),β=80.325(15),γ=78.738(14)°,Z=2,C24H17AgN2O4,Mr=505.27,Dc=1.698 g/cm3,μ=1.058 mm 1,F(000)=506,S=1.012 and T=293(2)K.The final R=0.0293 and wR=0.0667 for 3435 observed reflections with I>2σ(I),and R=0.0350 and wR=0.0688 for all data.
