| الملخص: | The Pb-II atom in the polymeric title compound, {[Pb(C13H11N4O)(CH3OH)(2)]ClO4} n, is coordinated by an N'-[1-(pyridin-2-yl-kappa N)ethylidene]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 supramolecular chain is a zigzag along the c axis. The Pb-II atom is seven-coordinated within an N3O3 donor set and a lone pair of electrons, which defines a Psi-pentagonal-bipyramidal coordination geometry with the pyridine N and lone pair in axial positions. The supramolecular chains are linked into the two-dimensional array via intermolecular Pb center dot center dot center dot N [3.020 (4) angstrom] interactions. Layers stack along the a axis, being connected by O-H center dot center dot center dot O hydrogen bonds formed between the coordinated methanol molecules and perchlorate anions. |
