Synthesis,Crystal Structure and Luminescent Property of 2D Network Lead(II),Complex

A new coordination polymer,[Pb(4,3-pybz)2]n(1),has been hydrothermally synthesized from Pb(CH3COO)2 ·3H2O and an unsymmetrical 4-pyridin-3-yl-benzoic acid(4,3-Hpybz),which is characterized by IR,elemental analysis,thermogravimetric analysis,and single crystal X-ray diffraction.This complex crystallizes in Orthorhombic,space group Pccn with a=1.070 74(7) nm,b=2.138 03(13) nm,c=0.865 65(5) nm,V=1.981 7(2) nm3,Z=4,Dc=2.023 Mg·m-3,F(000)=1 152,GOF=1.050,μ=8.549 mm-1,R1=0.013 9,wR2=0.032 4.Complex 1 shows a wavelike 2D coordination framework with(4,4) network topology,further through the weak π-π interaction formed a 3D supramolecular architectures.Furthermore,complex 1 shows weakly photoluminescent property at room temperature.
