Abstract

The influence of the solubility of AgNO3 in three solvent systems is studied for the reaction between AgNO3 and the ligand L (= ethanediyl bis(isonicotinate)). Three solid state structures are obtained, differing in the relative ratio Ag : L in the first case, and in polymorphism in the second. The Ag–O(NO3) distance correlates strongly with the solubility of AgNO3 in the used solvent. Solution studies prove indeed the existence of close ion contact pairs in the less good solvents, where as ion solvation is observed in good solvents for AgNO3. The three different structures are compared to two solvated structures in which H2O demonstrates coordination to the nitrate anion via H-bonding.
