In this contribution. two mononuclear molybdenum complexes with H2L tridentate (ONO) Schiff base ligand are characterized using computational techniques. Density functional theory (DFT) and its time extension (TD-DFT) calculations are performed to study the electronic structure in ground and excited state and to interpret the electronic absorption spectra in gas and aqueous phases.
