Abstract
We are focusing our synthetic and structural studies on thiadiazole derivatives and we have published recently the structure of 3-[5-(4-fluorophenyl)-1,3,4-thiadiazol-2-yl]-2phenylthiazolidin-4-one (Wan et al., 2006). We report the crystal structure of a close analog, (I), in which the 4-fluorophenyl substituent is replaced by 4-methoxyphenyl, and 2phenyl is replaced by 4-fluorophenyl. In (I), the thiazolidine ring adopts an envelope conformation with atom C7 at the tip of the flap (Fig. 1 and Table 1). There are intramolecular C— H S and intermolecular C—H O interactions (Table 2), forming chains along the b axis (Fig. 2).
