An understanding of methods to control the structure of self-assembled architectures is central to the efforts of chemists interested in self-assembly synthesis. Metal ions with square-planar geometry are a favorite of metallosupramolecular chemists, as there are only a limited number of possible ligand arrangements around the metal ion. Two such arrangements, firstly four monodentate donor sites (1,1,1,1), and secondly two monodentate donors and one bidentate donor (1,1,2) exemplify the symmetry interaction and ligand directed approaches, respectively. Symmetry interaction approaches using two bidentate sites (2,2) or a monodentate and tridentate site (1,3) have not received the same level of attention. In these arrangements, two complementary sites combine at the metal ion(s). This Minireview seeks to detail strategies employed to direct structure in systems with these arrangements, and is illustrated with key exemplars from the field.
理解控制自组装结构的方法对于对自组装合成感兴趣的化学家的工作至关重要。具有平面正方形几何结构的金属离子是金属超分子化学家的宠儿，因为围绕金属离子的可能配体排列数量有限。两种这样的排列，第一种是四个单齿供体位点（1,1,1,1），第二种是两个单齿供体和一个双齿供体（1,1,2），分别体现了对称相互作用和配体导向方法。使用两个双齿位点（2,2）或一个单齿和三齿位点（1,3）的对称相互作用方法尚未受到同等程度的关注。在这些排列中，两个互补位点在金属离子处结合。本综述旨在详细介绍在具有这些排列的体系中用于指导结构的策略，并通过该领域的关键示例进行说明。
