Structural inspection for Novel Pd (II), VO (II), Zn (II) and Cr (III)-Azomethine metal chelates: DNA interaction, Biological Screening and theoretical treatments

An alternative sequence of bioactive series, using novel Schiff base derivative (1-Quinolin-8-yliminomethyl-naphthalen-2-ol), was produced (HNQ). Elements analysis, molar conductivity, magnetic moment, IR, ¹H NMR, UV-Vis, and TGA were used to define the chemical forms. As a result, an appropriate geometry has been proposed for each complex. The HNQ ligand functions as a tri-dentate via NNO donors to the metal ions within octahedral geometry with Cr³⁺, square pyramidal with VO²⁺, tetrahedral with Zn²⁺, and square planner with Pd²⁺ ion.
