Spectroscopic, thermal analysis and DFT computational studies of salen-type Schiff base complexes

- A tetradentate salen-type Schiff base and its metal complexes were synthesized.
- The spectral and thermal properties of these complexes were studied.
- Compounds were characterized by IR, UV-Vis, NMR, as well as mass spectroscopy.
- The TG analyses suggest high stability for all complexes.
- The theoretical calculations were performed using different DFT methods.
