Abstract:
This work is focused in three topical subjects: intermolecular interactions, metal ions, and aromaticity. A comprehensive MP2/6-31 + G and B3LYP/6-31 + G study of the influence of cation-π interactions on the aromatic character of phosphole was conducted. For this purpose, the structures of complexes were optimized at both theoretical level and different magnetic properties were evaluated. The main conclusion is the increase of the aromatic character of the phosphole when complexes with Li(+), Be(2+), and Al(3+) are formed.
