Abstract

There are no direction-specific interactions between the molecules of 3-(2-methoxybenzyl)-2-(2-methoxyphenyl)-1,3-thiazolidin-4-one, C18H19NO3S, (I); the molecules of 3-(4-nitrobenzyl)-2-(4-nitrophenyl)-1,3-thiazolidin-4-one, C16H13N3O5S, (II), are linked by four independent C-H...O hydrogen bonds into complex chains of fused rings. In 3-(4-methoxybenzyl)-2-(4-methoxyphenyl)-1,3-thiazolidin-4-one, (III), isomeric with (I), the molecules are linked into sheets by a combination of C-H...O and C-H...p(arene) hydrogen bonds, while in 3-(2-nitrobenzyl)-2-(2-nitrophenyl)-1,3-thiazolidin-4-one, (IV), isomeric with (II), the sheets are built from three independent C-H...O hydrogen bonds and one C-H...p(arene) hydrogen bond, and reinforced by an aromatic p-p stacking interaction. In 3-(2-fluorobenzyl)-2-(2-fluorophenyl)-1,3-thiazolidin-4-one, C16H13F2NOS, (V), where the 2-aryl ring exhibits orientational disorder, the molecules are linked into sheets by a combination of C-H...O and C-H...p(arene) hydrogen bonds, and the sheets are linked in pairs, forming bilayers, by an aromatic p-p stacking interaction.
