A new coordination polymer, [Pb(4,3-pybz)(2)](n) (1), has been hydrothermally synthesized from Pb(CH3COO)(2)center dot 3H(2)O 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) nm(3), Z=4, D-c=2.023 Mg.m(-3), F(000)=1 152, GOF=1.050, mu=8.549 mm(-1), R-1=0.013 9, wR(2)=0.032 4. Complex 1 shows a wavelike 2D coordination framework with (4,4) network topology, further through the weak pi-pi interaction formed a 3D supramolecular architectures. Furthermore, complex 1 shows weakly photoluminescent property at room temperature. CCDC: 817928.
