چکیده
The Pb(II) atom in the polymeric title compound, {[Pb(C(13)H(11)N(4)O)(CH(3)OH)(2)]ClO(4)}(n), is coordinated by an N'-[1-(pyridin-2-yl-κN)ethyl-idene]isonicotinohydrazidate ligand via O,N,N'-donors and simultaneously bridged by a neighbouring ligand via the isonicotinoyl N atom; two additional sites are occupied by methanol O atoms. The resultant supra-molecular chain is a zigzag along the c axis. The Pb(II) atom is seven-coordinated within an N(3)O(3) donor set and a lone pair of electrons, which defines a Ψ-pentagonal-bipyramidal coordination geometry with the pyridine N and lone pair in axial positions. The supra-molecular chains are linked into the two-dimensional array via inter-molecular Pb⋯N [3.020 (4) Å] inter-actions. Layers stack along the a axis, being connected by O-H⋯O hydrogen bonds formed between the coordinated methanol mol-ecules and perchlorate anions.
