具有配位口袋线性排列的多(N)主题配体通常以较高的产率自组装，生成正方形[n×n]格子络合物。通过结构研究确定的低聚、非网格中间体，已经显示了替代的构建路径，但也表明了可能的网格组装的机械路径。各种因素被认为是网格形成的关键，包括反应pH、金属离子一致性、CFSE和金属离子氧化还原行为。最终，配体的设计是成功的网格自组装的关键，而[n x n]网格的大小在很大程度上仅受配体本身的合成限制。
Poly-(n)-topic ligands with a linear arrangement of coordination pockets self-assemble, generally in high yield, to produce square [n x n] grid complexes. Oligomeric, non-grid intermediates, identified by structural studies, have shown alternative construction pathways, but have also indicated possible mechanistic routes to grid assembly. Various factors are considered critical to grid formation, including reaction pH, metal ion identity, CFSE, and metal ion redox behaviour. Ultimately the design of the ligand is pivotal to successful grid self-assembly, and the size of the [n x n] grid is largely limited only by the synthetic limitations of the ligands themselves.
