Theoretical Study of the Interaction of Ethanol with the (3,5-Dimethylpyrazole-N2)(N-Salicylidenephenyl-Alaninato-O,N,O′)Copper(II) Complex

Аннотация

The electronic structure of the (3,5-dimethylpyrazole-N₂)(N-salicylidenephenyl-alaninato-O,N,O′)copper(II) complex and its ethanol adduct is calculated theoretically using different approaches. A comparison with X-ray data shows that M06/SVP and LC-BLYP/TZVP methods give the best theoretical geometry. The vibrational bands in the range 100–500 cm₋₁ are assigned by the aid of the Chemcraft software. Unrelaxed potential energy curves of the interaction of ethanol with our compound are obtained and examined.
