1,1'-Biisoquinolines are a class of bidentate nitrogen donor ligands in the heterocyclic diimine family. This review briefly discusses their properties and the key synthetic pathways available and then concentrates upon their coordination behaviour. The ligands are of interest as they exhibit the phenomenon of atropisomerism (hindered rotation about the C1-C1' bond). A notation for depicting the stereochemistry in coordination compounds containing multiple stereogenic centers is developed. The consequences of the chirality within the ligand on the coordination behaviour is discussed in detail.

1,1'-联异喹啉是杂环二亚胺家族中一类双齿氮供体配体。本文简要讨论了它们的性质和现有的关键合成途径，然后集中讨论了它们的配位行为。这些配体很有趣，因为它们表现出阻转异构现象（C1-C1' 键的旋转受阻）。开发了一种用于描述含有多个手性中心的配位化合物立体化学的符号表示法。详细讨论了配体内部手性对配位行为的影响。
