近年来，晶体工程的概念已经提供了许多合理设计的一维（1D）、二维（ZD）和三维（3D）聚合物结构的实例。包合化学特别感兴趣的是2D和3D配位聚合物，原则上至少可以将其设计为具有非常特定的孔径和类型。在这种情况下，已经存在分别由正方形-平面或三角形环境中的金属离子生成的2D正方形和六边形/蜂窝状网格的实例，其与线性双官能配体如4，4 '-联吡啶或吡嗪配位。此外，已经通过配位共价键或氢键生成了基于四面体或S1配位环境的3D类金刚石配位聚合物。[41然而.考虑到八面体金属环境的普遍性。有些令人惊讶的是，简单的3D八面体聚合物[51]仍然在很大程度上未被开发。实际上，据我们所知，p-氰基聚合物如Fe&I[Fe（CN）2]、普鲁士蓝[61]、表征不佳的[Cd（CN）2]、[Cd（CN）2]、[Cd（CN）2]和三重互穿的[Cd（吡嗪）2]（Ag（CN）2）代表了此类结构的仅有实例。[9a1最近合成了一种吡嗪与银离子的配位聚合物，并对其结构进行了表征。[gb1在这篇文章中，我们详细介绍了一个潜在的一般战略，产生这样的聚合物。方案1说明了阳离子方形网格与合适的线性双官能阴离子配体的交联如何可以在印刷中进行。
The concept of crystal engineering"' has in recent years provided numerous examples of rationally designed one(1 D), two(ZD), and three-dimensional (3D) polymeric structures. Of particular potential interest to inclusion chemistry are 2D and 3D coordination polymers which, in principle a t least, can be designed to have very specific pore size and type. In such a context, there already exist examples of 2D square"] and hexagonal/ honeycornbC3l grids generated from metal ions in square-planar or trigonal environments, respectively, coordinated to linear bifunctional ligands such as 4.4'-bipyridine or pyrazines. Furthermore, 3D diamondoid coordination polymers based upon tetrahedral or S, coordination environments have been generated by either coordinate covalent bonds or hydrogen bonding.[41 However. given the ubiquity of octahedral metal environments. it is somewhat surprising that simple 3D octahedral polymers[51 remain largely unexplored. Indeed, to our knowledge p-cyano polymers such as Fe&I[Fe"(CN),],, Prussian Blue,[61 the poorly characterized [Cd(CN),(q~inoxaline)],,,['~ and triply interpenetrated [Cd(pyrazine)(Ag,(CN),)(Ag(CN),)llsl represent the only examples of such structures.[9a1 Recently a coordination polymer from silver ions and pyrazine was synthesized and structurally characterized.[gb1 In this contribution we detail a potentially general strategy for generation of such polymers. Scheme 1 illustrates how cross-linking of cationic square grids with suitable linear bifunctional anionic ligands could in prin-
