13C NMR and IR Evidence for the Two Types of Copper(I) and (II) Complexes with 5-Pyrido-1,4-benzodiazepin-2-ones

Autor: Vitomir Šunjić, Vladimir Vinković, Zlata Raza

Publikováno v: Spectroscopy Letters. 27:269-279

5-Pyrido-1,4-benzodiazepin-2-onederivatives 1–9 are investigated as potential 1,4-N,N-bidentate ligands in copper(I) and (II) complexes. On the basis of 13C NMR and IR spectra two types of complexation are revealed. In the first ones, ligands 1–5
