A novel metal-organic framework(MOF) compound of Pb(C5H4NCOO)2 was hydrothermally synthesized and structurally determined by X-ray single-crystal diffraction. The data of unit cell:orthorhombic space group Pccn,a=1.0325(2) nm,b=1.3597(3) nm,c=0.8499(2) nm,V=1.1931(4) nm3,Z=4,Dc=2.513 g/cm3,R1=0.047 were obtained on the basis of 1365 reflections with Fo>2σ(Fo). PbN2O6 polyhedron adopts the distorted cubic configuration which is assigned to the holodirected geometry. These PbN2O6 polyhedra can form the zigzag chain by edge-sharing mode along(001) direction. Pb atom is connected by six nicotinic acid molecules,leading neutral 3D metal-organic framework with a channel defined by four Pb atoms and four nicotinic acid molecules.
