WebNov 6, 1997 · But when the aluminium plus a modifier are used as a coupled substitution for silicon, it was believed that no non-bridging oxygens should be produced and a fully connected network with a... Web4,4′-Dithiodipyridine (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 dtdp ligand have been crystallographically characterised until now. This …
