(5Z)-5-(2-Hydroxybenzylidene)-3-phenyl-2-thioxo-1,3-thiazolidin-4-one
In the title compound, C(16)H(11)NO(2)S(2), the dihedral angles between the heterocyclic ring and the phenyl and anilinic benzene rings are 9.68 (13) and 79.26 (6)°, respectively, and an intra-molecular C-H⋯S inter-action occurs. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds occur, leading to R(2) (2)(10) loops, and C-H⋯O and weak C-H⋯π inter-actions further consolida...
متن کامل(1R,2S,5R)-(–)-Menthyl (S)-2-(methoxycarbonyl)benzenesulfinate
In the title chiral sulfinic acid ester, C18H26O4S, the cyclo-hexane ring of the menthyl fragment adopts a chair conformation. The mol-ecular shape is defined by the dihedral angle of 47.87 (8)° between the mean planes of the cyclo-hexane and benzene rings. In the crystal, mol-ecules related by the screw axis are connected into chains along [010] by weak Car-H⋯O=S contacts.

The title compound, C(23)H(31)O(2)P, has three fully extended substituents around the P-atom chiral centre, forming an S(P) configuration. The phenyl rings are inclined at a dihedral angle of 3.2 (3)°.
متن کامل(5Z)-5-(2-Methylbenzylidene)-3-phenyl-2-thioxo-1,3-thiazolidin-4-one
In the title compound, C(17)H(13)NOS(2), the heterocyclic ring is oriented at a dihedral angle of 74.43 (5)° with respect to the anilinic benzene ring and at a dihedral angle of 17.31 (9)° with respect to phenyl ring. An intra-molecular C-H⋯S inter-action occurs, resulting in an S(6) ring. In the crystal, the packing is consolidated by C-H⋯π inter-actions and possible very weak aromatic π-π sta...
