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.
在聚合标题化合物{[Pb(C₁₃H₁₁N₄O)(CH₃OH)₂]ClO₄}ₙ中，Pb(II)原子通过O、N、N'供体与N'-[1-(吡啶-2-基-κN)亚乙基]异烟酰肼配体配位，并同时通过异烟酰基N原子被相邻配体桥连；另外两个位置被甲醇O原子占据。所得的超分子链沿c轴呈锯齿状。Pb(II)原子在一个由N(3)O(3)供体集和一对孤对电子构成的环境中呈七配位，这定义了一种ψ-五角双锥配位几何构型，其中吡啶N和孤对电子处于轴向位置。超分子链通过分子间Pb⋯N [3.020 (4) Å]相互作用连接成二维阵列。层沿着a轴堆叠，通过配位甲醇分子与高氯酸根阴离子之间形成的O-H⋯O氢键相连。
