Redetermination of the crystal structure of 2-oxo-1,3-thiazolidin-4-iminium chloride

Abstract

In the redetermination of the title compound, C 3 H 5 N 2 OS + CI - , the asymmetric unit consists of one independent 2-oxo-1,3-thiazolidin-4-iminium cation and one independent chloride anion. The cation interacts with a chloride anion via N-H Cl hydrogen bonds forming a supramolecular chain along [010]. These supramolecular chains are further extended by weak C-H Cl and C-H O interactions, forming a two-dimensional network parallel to (001). The crystal structure is further stabilized by weak C-O π interactions, supporting a three-dimensional architecture. The structure was previously determined by Ananthamurthy & Murthy [Z. Kristallogr. (1975). 8, 356-367] but has been redetermined with higher precision to allow the hydrogen-bonding patterns and supramolecular interactions to be investigated.
