(Z)-3-(2-Hy-droxy-eth-yl)-2-(phenyl-imino)-1,3-thia-zolidin-4-one.

In the title compound, C(11)H(12)N(2)O(2)S, the thia-zole and phenyl rings are inclined at 56.99 (6)° to one another. The thia-zole ring is planar with an r.m.s. deviation for the five ring atoms of 0.0274 Å. The presence of the phenyl-imine substituent is confirmed with the C=N distance to the thia-zole ring of 1.2638 (19) Å. The mol-ecule adopts a Z conformation with respect to this bond. The -OH group of the hy-droxy-ethyl substituent is disordered over two positions with relative occupancies 0.517 (4) and 0.483 (4). In the crystal, O-H⋯O hydrogen bonds, augmented by C-H⋯N contacts, form dimers with R(2) (2)(11) rings and generate chains along the b axis. Parallel chains are linked in an obverse fashion by weak C-H⋯S hydrogen bonds. C-H⋯O hydrogen bonds together with C-H⋯π contacts further consolidate the structure, stacking mol-ecules along the b axis.
