(Z)-4-(2-Hy-droxy-benzyl-idene)-1-methyl-2-phenyl-1H-imidazol-5(4H)-one.

ABSTRACT: In the title compound, C(17)H(14)N(2)O(2), the asymmetric unit comprises two mol-ecules that are comformationally similar [the dihedral angles between the phenyl rings in each are 46.35 (2) and 48.04 (3)°], with the conformation stabilized by intra-molecular O-H⋯N hydrogen bonds, which generate S(7) rings. In the crystal, inversion-related mol-ecules are linked by pairs of weak C-H⋯O hydrogen bonds, forming dimers with an R(2) (2)(16) graph-set motif. Weak inter-ring π-π stacking is observed in the structure, the shortest centroid-to-centroid distance being 3.7480 (13) Å.

Project description:In the title compound, C14H16N2O3, an analog of the chromophore in green fluorescent protein, the meth-oxy-phenyl substituent and the imidazole N adopt a Z conformation with respect to the C=C bond. Aside from the hy-droxy-ethyl group, the mol-ecule is approximately planar, with the five- and six-membered ring planes forming a dihedral angle of 9.3 (1)°. An intra-molecular C-H⋯N contact occurs. In the crystal, O-H⋯N hydrogen bonds link the mol-ecules, forming chains along the b-axis direction. C-H⋯O hydrogen bonds are also observed.

Project description:The title compound, C10H10N4OS, is nearly planar with the mean planes of the hy-droxy-benzyl and triazole rings inclined at an angle of only 3.2 (7)°. In the crystal, O-H⋯N hydrogen bonds between the hy-droxy group and the triazole ring in concert with weak N-H⋯S inter-molecular inter-actions between the triazole ring and thione group form chains along [-210] enclosing R 2 (2)(8) graph-set motifs. A weak intra-molecular C-H⋯S inter-action and inter-molecular π-π inter-actions [centroid-centroid distance = 3.5990 (15) Å] are also observed.

Crystal structure of 4-[(E)-(4-hy-droxy-benzyl-idene)amino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one.

Project description:The asymmetric unit of the title compound, C18H17N3O2, comprises three independent mol-ecules (1, 2 and 3). In mol-ecule 1, the dihedral angles between the pyrazolone ring and the pendant phenyl and hydroxybenzene rings are 54.43 (6) and 28.72 (6)°, respectively. The corresponding data for mol-ecule 2 are 86.84 (6) and 25.69 (5)°, respectively, and for mol-ecule 3 are 47.41 (7) and 17.09 (7)°, respectively. The three mol-ecules feature an intra-molecular C-H⋯O inter-action, which closes an S(6) ring in each case. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, which generate [100] chains incorporating all three asymmetric mol-ecules. Two weak C-H⋯O interactions connect three independent molecules to each other along the c-axis direction.
