1-Acetyl-4-(phenylsulfanyl)imidazolidin-2-one
The five-membered ring in the title imidazolidinone derivative, C(11)H(12)N(2)O(2)S, adopts an envelope conformation with the S-bound C atom being the flap atom. Overall, the mol-ecule has a U-shaped conformation as both rings are folded towards each other [dihedral angle = 31.66 (6)°]. An eight-membered amide {⋯HNCO}(2) synthon leads to hydrogen-bonded dimeric aggregates in the crystal: these ...
متن کامل1-Acetyl-5-(4-fluorophenyl)-2-sulfanylideneimidazolidin-4-one
In the title compound, C11H9FN2O2S, the 2-sulfanylideneimidazolidin-4-one moiety is essentially planar, with a maximum deviation of 0.0183 (14) Å. The mean plane of this moiety is approximately coplanar with the attached acetyl group and perpendicular to the benzene ring, making dihedral angles of 9.70 (14) and 86.70 (6)°, respectively. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bo...
متن کاملrac-1-Acetyl-5-benzyl-2-thioxoimidazolidin-4-one
In the title compound, C(12)H(12)N(2)O(2)S, the mol-ecules have a wing-like conformation, with a distance of 3.797 (2) Å between the centroids of the five- and six-membered rings. In the crystal structure, mol-ecules are linked by N-H⋯O hydrogen bonds, forming infinite one-dimensional zigzag chains, running along [001], with a C(4) graph-set motif.
متن کامل1-Acetyl-5-methoxy-4-(phenylsulfanyl)imidazolidin-2-one
The title compound, C12H14N2O3S, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The five-membered imidazolidin-2-one rings in both mol-ecules are twisted about the C-C bond. In the crystal, the A and B mol-ecules are associated via pairs of N-H⋯O hydrogen bonds, forming A-B dimers. These dimers are linked via C-H⋯S hydrogen bonds, forming double dimers, which are...
متن کامل3-Acetyl-4-hydroxy-6,7-dimethyl-2H-chromen-2-one
In the title coumarin derivative, C(13)H(12)O(4), the 2H-chromene ring system is essentially planar [maximum deviation = 0.047 (1) Å]. An intra-molecular hydrogen bond is observed between the hy-droxy and the ketonic O atoms. In the crystal, pairs of inter-molecular C-H⋯O hydrogen bonds link inversion-related mol-ecules into dimers. Additional inter-molecular C-H⋯O hydrogen bonds further inter-...
