Crystal structure of (E)-3-allyl-2-sulfanylidene-5-[(thiophen-2-yl)methylidene]thiazolidin-4-one
Mol-ecules of the title compound, C11H9NOS3, are built up by one thio-phene and one 2-thioxa-thia-zolidin-4-one ring which are connected by a methyl-ene bridge. In addition, there is an allyl substituent attached to nitro-gen. The two rings are almost coplanar, making a dihedral angle between them of 0.76 (11)°. The allyl group is oriented perpendicular to the mean plane through both ring syste...

متن کاملCrystal structure of (E)-3-(5-bromo-2-hydroxyphenyl)acrylaldehyde
The title compound, C9H7BrO2, displays a trans configuration with respect to the C=C double bond and is essentially planar [maximum deviation from the least-squares plane through all non-H atoms = 0.056 (4) Å]. The vinyl-aldehyde group adopts an extended conformation wih a C-C-C-C torsion angle of 179.7 (4)°. In the crystal, mol-ecules are linked by classical O-H⋯O and weak C-H⋯O hydrogen bonds...
متن کاملCrystal structure of 4-[(E)-(2-carbamothioylhydrazinylidene)methyl]benzoic acid
The title compound, C9H9N3O2S, is close to planar with an r.m.s. deviation of 0.032 Å. An intra-molecular N-H⋯N hydrogen bond closes an S(5) ring. In the crystal, mol-ecules are connected into inversion dimers of the R 2 (2)(8) type by pairs of O-H⋯O inter-actions. The dimers are further connected by pairs of N-H⋯S inter-actions, which also complete R 2 (2)(8) ring motifs. The chains of dimers ...
