Synthesis and Physicochemical Properties of Cu(II), Co(II), and Cd Complexes with Oximes of 3,4-Dihydroisoquinoline Derivatives

Complex compounds MX2L H2O, where M = Cu), Co(II), or Cd; X = Cl- or NO3 -; L = bis(3,3-dimethyl-3,4-dihydroisoquinolyl-1) ketone oxime or (3,3-dimethyl-3,4-dihydroisoquinolyl-1)hydroxyiminoacetamide were synthesized. It is shown that the ligands are incorporated into the complexes as an oxime tautomer in the molecular form. On the basis of IR and electronic absorption spectra, it is concluded that the cyclic nitrogen atom is involved in the formation of metal-ligand bonds.
