The Pb-II atom in the polymeric title compound, {[Pb(C13H11N4O)]ClO4}(n), is coordinated by the N'-[1(-pyridin-2-yl-kappa N)ethylidene]isonicotinohydrazidate ligand via its O,N,N'-donors and simultaneously bridged by a neighbouring ligand via the pyridin-2-yl N atom. The resultant supramolecular chain is a zigzag along the a axis. The stereochemistry of the Pb-II atom is defined by an N3OE donor set (E = lone pair of electrons), which results in a Psi-trigonal-bipyramidal coordination with the O and pyridin-2-yl N atoms in axial positions. The dihedral angle between the pyridine rings of the ligand is 6.3 (3)degrees. The supramolecular cationic chains are linked into a three-dimensional array via secondary Pb center dot center dot center dot O [3.133 (6) and 3.28 (7) angstrom] and Pb center dot center dot center dot N [3.028 (4) angstrom] interactions. Weak C-H center dot center dot center dot O interactions and aromatic pi-pi stacking [centroid-centroid separation = 3.693 (2) angstrom] also occur in the crystal.
