Abstract

In the title polymer, ZnCl(2)(C(11)H(8)N(2)O), the Zn(II) atom lies on a twofold rotation axis and has a distorted tetra-hedral ZnCl(2)N(2) geometry involving two chloride donors and two N-atom donors from μ(2)-bridging bis-(pyridin-3-yl)methanone ligands, which also have twofold symmetry. A zigzag chain structure is formed, extending along (001). Each chain is surrounded by three others which are inter-connected through weak C=O⋯π(pyrid-yl) [O⋯centroid = 2.999 (3) Å] and π(pyrid-yl)-π(pyrid-yl) inter-actions [minimum ring centroid separation = 4.014 (2) Å], giving a three-dimensional framework.

摘要

在标题聚合物[ZnCl₂(C₁₁H₈N₂O)]ₙ中，Zn(II)原子位于一个二重旋转轴上，具有扭曲的四面体ZnCl₂N₂几何构型，涉及两个氯供体和来自μ₂-桥连双-(吡啶-3-基)甲酮配体的两个氮原子供体，该配体也具有二重对称性。形成了一个锯齿链结构，沿(001)方向延伸。每条链被另外三条链包围，它们通过弱的C=O⋯π(吡啶基)[O⋯质心 = 2.999 (3) Å]和π(吡啶基)-π(吡啶基)相互作用[最小环质心间距 = 4.014 (2) Å]相互连接，形成三维框架。
