Structural, Spectroscopic and Activity Calculations on Methanesulfonylhydrazone Derivative Chromium Pentacarbonyl Complexes
Abstract
The thiophene-2-carboxyaldehyde methanesulfonylhydrazone (msh1), 2-acetylthiophene methanesulfonylhydrazone (msh2) and 2-acetyl-5-methylthiophene methanesulfonylhydrazone (msh3) ligands, a heteroatomic methanesulfonylhydrazone derivative, was optimized by using HF and DFT (B3LYP) method with 6-31G(d,p) basis set. The calculated IR spectra for msh1, msh2 and msh3 were compared with experimental data and the suitability of the calculation methods was discussed. LANL2DZ and GEN basis sets were used for calculations of chromium pentacarbonyl complexes containing msh1, msh2 and msh3 ligands. According to the experimental IR spectra the most appropriate method and basis set was determined. Structural parameters of ligands and complexes were predicted. To investigate the biological activities of ligands and complexes, some activity descriptors were obtained from optimized structures. Molecular electrostatic potential (MEP) maps of the mentioned ligands and complexes were examined and active sites were determined. The molecular docking study of ligands and complexes with Bacillus cereus (PDB ID=5V8E), Staphylococcus aureus (PDB ID=1BQB), and Candida albicans (PDB ID=1AI9) were performed.
