Abstract

In the mononuclear title complex, [Ag(C(10)H(6)N(4))(2)]ClO(4), the Ag(I) ion is surrounded by two 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands, forming a considerably distorted square-planar N(4)-coordination geometry, with two short and two long Ag-N distances. Each perchlorate anion links two mononuclear coordination units through C-H⋯O(perchlorate) hydrogen bonding, forming an infinite tape structure along [110]. Inter-molecular π-π stacking inter-actions between adjacent pyridine and pyrazine rings [centroid-centroid distances of 3.777 (3) and 3.879 (2) Å] further assemble the tape motifs into a three-dimensional supra-molecular structure.

摘要

在单核标题配合物[Ag(C₁₀H₆N₄)₂]ClO₄中，Ag(I)离子被两个5-(吡啶-2-基)吡嗪-2-甲腈配体包围，形成一个严重扭曲的平面正方形N₄配位几何结构，有两个短的和两个长的Ag-N距离。每个高氯酸根阴离子通过C-H⋯O(高氯酸根)氢键连接两个单核配位单元，沿[110]形成无限的带状结构。相邻吡啶环和吡嗪环之间的分子间π-π堆积相互作用[质心-质心距离为3.777 (3)和3.879 (2) Å]进一步将带状结构组装成三维超分子结构。
