 Title    N NQR and the Molecular Charge Topology in Coordinated Ammonia  
 Abstract    14 N NQR spectra of [Co(NH3)6] • 3C1, [Co(NH3)5C03] • N03, [Zn(NH3)4] • 2C1, [Zn(NH3)4] • (BF4)2, and [Ag(NH3)4] • N03 were obtained at 77 K. The results, analyzed by means of the topology of the charge distribution obtained from ab-initio MO calculations of free and of a model of coordinated NH3, showed that bonding to the metal-ion produces a strong decrease (Co^>Zn %Ag) in the N nonbonded density ("lone pair") and an increase in the bonded maxima found in the N-H bond direction of the N valence shell.
