Resumo
dy of Phosphorus Ion Complexes of Ammonia andWater. — By ab initio calculations for the P(NH3)+ n, P(OH2)+ n (n= 1, 2) and P(NH3)(OH2)+ ion-molecule complexes, optimum geometries(HF/6-31G** and MP2/6-31G*), binding energies (at different levels of theory)and Mulliken charges are determined. The binding energies for the oneligand complexes are larger than those expected from an electrostatic bindingmechanism. This is ascribed to some electron dative bonding character. Forthe two-ligand complexes binding energies closer to the electrostatic ones areobtained indicating a higher electrostatic character than that of the one-ligandcomplexes.
