Synthesis, characterization, and DFT calculation of a Pd(II) Schiff base complex

Comparison between the calculated and experimental results covering molecular structures, assignment of fundamental vibrational modes, and thermodynamic properties were investigated. The optimized molecular geometries were compared with the experimental data obtained from X-ray data of a similar complex, which indicated that the theoretical results agree with the corresponding experimental values. The UV-Vis spectrum of the compound was also recorded and some properties, such as HOMO and LUMO energies and λmax , were determined using DFT (PW91) method. The absorption wavelengths were compared with the experimental data.
