Abstract
A study of the absorption spectra of copper(II and I)-2,2′-biquinoline complexes in acetonic media has revealed that in the presence of excess ligand the predominant structure for both oxidation states of copper is probably that of a trigonal bipyramid. A crystalline monobiquinoline complex containing pseudo-octahedrally coordinated copper(II) has been isolated from solutions containing chloride ion. Evidence has been obtained that suggests the existence of a tris-biquinoline–copper(I) complex in which one biquinoline acts as a monodentate ligand.Keywords
