• 4,4'-Dithiodipyridine \(\textbf {(dtdp)}\), also termed 4,4'-dipyridyldisulfide, is a bridging ligand of the 4,4'-bipyridine type. The introduction of the disulfide moiety inevitably leads to a relatively rigid angular structure, which exhibits axial chirality. More than 90 metal complexes containing the \(\bf dtdp\) ligand have been crystallographically characterised until now. This review focuses on the preparation and structural diversity of discrete and polymeric metallosupramolecular assemblies constructed from \(\bf dtdp\) as bridging ligands. These encompass metallamacrocycles with \(M_{2}L_{2}\) topology and coordination polymers with periodicity in one or two dimensions. One-dimensional coordination polymers represent the vast majority of the metallosupramolecular structures obtained from \(\bf dtdp\). These include repeated rhomboids, zigzag, helical and arched chains among other types. In this contribution, we make an attempt to provide a comprehensive account of the structural data that are currently available for metallosupramolecular assemblies based on the bent bridging ligand \(\bf dtdp\).
