Crystal structure of methyl ( Z )-2-[( Z )-3-methyl-2-({( E )-1-[( R *)-4-methylcyclohex-3-en-1-yl]ethylidene}hydrazinylidene)-4-oxothiazolidin-5-ylidene]acetate
Abstract : The new title 4-thiazolidinone derivative, C16H21N3O3S, was obtained from the cyclization reaction of 4-methyl-3-thiosemicarbazone and dimethyl acetylenedicarboxylate (DMAD). The cyclohexylidene ring has an envelope conformation with the stereogenic centre C atom as the flap. Its mean plane makes a dihedral angle of 56.23 (9)° with the thiazolidine ring mean plane. In the crystal, molecules are linked by C—HO hydrogen bonds forming chains propagating in the [001] direction. Within the chains there are offset π–π interactions between the thiazolidine rings of inversion-related molecules [centroid–centroid distance = 3.703 (1) Å]. The chains are linked by further C—HO hydrogen bonds, forming slabs parallel to the ac plane.
