The title compound, C16H16N4O2, crystallizes with two mol-ecules in the asymmetric unit, one of which shows disorder of the acetate group over two sets of sites in a 0.799 (2):0.201 (2) ratio. The phenyl group has a similar but opposite sense of twist relative to the pyrazole ring in the two mol-ecules, as indicated by the syn N-N-Car-Car (ar = aromatic) torsion angles of 39.7 (2) and -36.9 (2)...

The asymmetric unit of the title compound, C10H14N2O3, contains two independent mol-ecules with similar conformations. In the both mol-ecules, the cyclo-hexene rings adopt the same envelope conformation with the flap C atoms lying 0.658 (3) and 0.668 (3) Å from the mean planes formed by the remaining atoms. In the crystal, adjacent mol-ecules are connected via N-H⋯O hydrogen bonds and weak C-H⋯...

In the title compound, C17H17N3O3S, the thia-zole ring is nearly planar [maximum deviation = 0.015 (1) Å for the ring N atom] and the cyclo-pentane ring has a twist conformation. The mol-ecular conformation is stabilized by a hypervalent inter-action between the S atom and the ester group carbonyl O atom, with an S⋯O distance of 2.7931 (10) Å. In the crystal, C-H⋯O inter-actions generate chains...
متن کاملCrystal structure of 3-[(E)-(2-hydroxy-3-methoxybenzylidene)amino]-1-methyl-1-phenylthiourea
In the asymmetric unit of the title compound, C16H17N3O2S, there are two independent mol-ecules (A and B), which show an E conformation with respect to the C=N bond. An intra-molecular O-H⋯N hydrogen bond with an S(6) motif stabilizes the mol-ecular structure. The terminal phenyl and benzene rings are almost orthogonal to each other, the dihedral angle being 87.47 (13)° for mol-ecule A and 89.8...
