(Z)-5-(4-Fluoro-benzyl-idene)-1,3-thia-zolidine-2,4-dione.

ABSTRACT: In the title compound, C(10)H(6)FNO(2)S, the benzene and thia-zolidine rings make a dihedral angle of 7.52?(3)°. Intra-molecular C-H?O and C-H?S hydrogen bonds result in the formation of nearly planar five- and six-membered rings; the adjacent rings are nearly coplanar. In the crystal structure, inter-molecular N-H?O hydrogen bonds link the mol-ecules.
