New complexes MCl2L · H2O and CuX2L, where M = Co(II) or Zn; X = Cl- or Br-; L = 3,3-dimethyl-3,4-dihydroisocarbostyril azine, were synthesized. The structure of isolated compounds is discussed on the basis of IR and electronic absorption spectra and quantum-chemical calculations of L tautomers in molecular and protonated forms.
