چکیده
The title compound, C(16)H(14)N(2)O(2), was derived from 1-(2-hydroxy-phen-yl)-3-(2-methoxy-phen-yl)propane-1,3-dione. The mol-ecule is essentially planar (r.m.s. deviation for all non-H atoms = 0.089 Å). Two intra-molecular hydrogen bonds stabilize the mol-ecular conformation and one N-H⋯O hydrogen bond stabilizes the crystal structure.

The title compound, C(21)H(16)N(2)O(2), was derived from 1-(2-hydroxy-phen-yl)-3-(4-methoxy-phen-yl)propane-1,3-dione. The pyrazole ring and one of the hydr-oxy-substituted benzene rings are approximately coplanar, forming a dihedral angle of 7.5 (3)°. The relative conformation of these rings may be influenced by an intra-molecular O-H⋯N hydrogen bond. In the crystal structure, inter-molecular ...

In the title compound, C(18)H(15)ClN(4)O(2)S, the pyrazole ring makes dihedral angles of 67.4 (1) and 12.5 (1)° with the phenyl and 4-hydroxy-phenyl groups, respectively; the two benzene rings are twisted by 60.1 (1)° with respect to each other. The thio-urea NH groups are involved in N-H⋯O and N-H⋯Cl intra-molecular hydrogen bonds. A hydrogen bond between the phenolic OH group and the pyrazole...
