2-(2,4-Dichloro-phen-yl)-3-[5-(4-methoxy-phen-yl)-1,3,4-thia-diazol-2-yl]-1,3-thia-zolidin-4-one.

ABSTRACT: In the mol-ecule of the title compound, C(18)H(13)Cl(2)N(3)O(2)S(2), the thia-zolidinone ring has an envelope conformation with the S atom displaced by 0.394?(3)?Å from the plane of the other ring atoms. The thia-diazole ring is oriented at a dihedral angle of 7.40?(4)° with respect to the 4-methoxy-phenyl ring. Intra-molecular C-H?S, C-H?N and C-H?Cl hydrogen bonds result in the formation of two planar and two non-planar five-membered rings. The planar five-membered rings are oriented at a dihedral angle of 6.23?(3)°. The 2,4-dichloro-phenyl ring is oriented at dihedral angles of 84.21?(4) and 83.55?(3)° with respect to the thia-diazole and 4-methoxy-phenyl rings, respectively. In the crystal structure, inter-molecular C-H?O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
