This paper describes the preparation and characterization of some comp
lex Cu(II) combinations with pyridil-azonaphthol (PAN) and p-nitrobenz
ene-azoresorcinor (NAR) ligands. The IR-UV-VIS and RES spectra were do
ne in order to establish the stereochemistry of these complex combinat
ions. Based on the data thus obtained, the newly synthetized formulati
ons were attributed formulations of the distorted tetrahedric symmetry
group.
