Abstract
A new R-0 value for Na-O bonds of 1.756(42) Angstrom was determined from 30 1 NaOn complexes. The bend valence sum analysis suggests a covalent interac tion of the Na+ ion with aromatic rings and/or organic anions. The BVS anal ysis of Na(15-crown-5)(+) cation complexes requires additional bonding inte ractions which can be used to explain the enhanced stability of the cation complex both in solution and in the solid state relative to that in the gas phase.
