The preparations and properties of fifty-three new complexes
of Cobalt (II), Nickel (II), Copper (II) and Copper (I) halides and
nitrates are described. The ligands used were 3-Bromopyridine,
4-Chloropyridine, 1:2:4-Triazole, Quinoxaline, 2-Methylquinoxaline,
2:3-Dimethylquinoxaline, 2:3-Diphenylquinoxaline and Phenazine.
The electronic reflectance spectra of these complexes have been
measured, and the spin-allowed transitions assigned. The calculated
ligand-field parameters are compared with those of related complexes,
and the value of such calculations assessed. The spectra, along
with confirmatory magnetic and infrared data are used to elucidate
the stereochemistries of the complexes. [Continues.]
