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

چکیده
The new title 4-thia-zolidinone derivative, C16H21N3O3S, was obtained from the cyclization reaction of 4-methyl-3-thio-semicarbazone and dimethyl acetyl-enedi-carboxyl-ate (DMAD). The cyclo-hexyl-idene 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 thia-zolidine ring mean plane. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds forming chains propagating in the [001] direction. Within the chains there are offset π-π inter-actions between the thia-zolidine rings of inversion-related mol-ecules [centroid-centroid distance = 3.703 (1) Å]. The chains are linked by further C-H⋯O hydrogen bonds, forming slabs parallel to the ac plane.

The crystal structure and the conformation of the title compound, C22H27N3O7S, were determined from the synthetic pathway and by X-ray analysis. This compound is a new 4-thia-zolidinone derivative prepared and isolated as pure product from thio-semicarbazone carvone. The mol-ecule is built up from an oxo-thia-zolidine ring tetra-substituted by a meth-oxy-oxo-ethyl-idene, a maleate, an oxygen an...

The title complex, [Cu(C22H19N2O3S2)2], was obtained from the reaction between (Z)-methyl 2-(5-benzyl-imino-4-benzyl-carbamo-thioyl-3-oxo-thio-lan-2-yl-idene)acetate and Cu(NO3)2. The Cu(II) atom is tetra-coordinated by two N,S-bidentate ligands, forming a highly distorted tetra-hedral environment. The structure displays two intra-molecular N-H⋯O hydrogen bonds.

In the title compound, C45H40N4O5, the cyclo-hexane entity on the (3-cyano-2,5-dihydro-furan-2-yl-idene)propane-dinitrile group, which replaces the usual dimethyl substituents, has not perturbed the delocalization geometry significantly. Weak inter-molecular inter-actions, viz. C-H⋯N(cyano), C-H⋯O(ether), C-H⋯π and π-π [between the aromatic rings with the shortest centroid-centroid distance of ...
