Abstract
The literature pertaining to tri-, tetra-, penta-, and hexadentate amine ligands containing unsubstituted quinoline moieties is reviewed. The syntheses of these 46 ligands are detailed, and all X-ray structurally characterised transition metal complexes of these ligands are compiled and discussed. Comparisons to the analogous pyridine complexes, where they exist, are made. Most differences are found amongst the five-coordinate complexes, where the quinoline complexes mostly exhibit square pyramidal geometries, while the analogous pyridine complexes are predominantly trigonal bipyramidal. A structural feature we term the quinolyl split, where one or two quinolyl rings bisect an X-M-X angle, in contrast to their pyridine congeners, is identified.Description
