Structural, spectral, NLO and MEP analysis. of the [MgO2Ti2(OPri)(6)], [MgO2Ti2(OPri)(2)(acac)(4)] and [MgO2Ti2(OPri)(2)(bzac)(4)] by DFT method
Quantum chemical calculations are performed on [MgO2Ti2(OPri)(6)] and [MgO2Ti2(OPri)(2)(L)(4)] complexes. L is acetylacetonate (acac) and benzoylacetonate (bzac) anion. The crystal structures of these complexes have not been obtained as experimentally but optimized structures of these complexes are obtained as theoretically in this study. Universal force field CUFF) and DFT/B3LYP method are used to obtain optimized structures. Theoretical spectral analysis (IR, H-1 and C-13 NMR) is compared with their experimental values. A good agreement is found between experimental and theoretical spectral analysis. These results mean that the optimized structures of mentioned complexes are appropriate. Additionally, the active sites of mentioned complexes are determined by molecular electrostatic potential (MEP) diagrams and non-linear optical (NLO) properties are investigated.
