Abstract

Five derivatives of thioisocoumarin bearing aromatic and nonaromatic ring systems have been synthesized and characterized to unravel the importance of interactions due to the presence of a sulfur atom in generating packing motifs in the crystalline state. Apart from the well characterized interactions like C-H center dot center dot center dot S, a C=S center dot center dot center dot pi interaction is found in one of the case studies. The importance of such interactions in crystal structure packing along with routine C-H center dot center dot center dot pi and pi center dot center dot center dot pi interactions is examined in the context of overall stability in the molecular assembly. The C=S center dot center dot center dot pi interactions in comparison to C=O center dot center dot center dot pi interactions have been analyzed using the Cambridge Structural Database (CSD).
