Hydrate formation in NH+-containing salts of pharmaceutically acceptable anions: A CSD survey

Abstract

The CSD has been systematically searched for salts of N-based cations and pharmaceutically acceptable groups of anions. The tendency of particular anions to crystallise with particular cations has been assessed, and the occurrence of hydrates within particular groups of salts has been analysed. It was found that pyridinium carboxylate salts show a reduced tendency to form hydrates when compared to other salts.
