✦ Synopsis
The title compound, C~18~H~15~N~3~O, was prepared from phenyl(1__H__-pyrrol-2-ylmethylene)amine and phenyl isocyanate in the presence of catalytic amounts of [Pd(PPh~3~)~4~]. The conformation of the molecular structure is determined by an intramolecular hydrogen bond between the amide NH function and the imine N atom. The molecule is essentially planar. Only the peripheral phenyl substitutents are bent out of the plane.

In the title compound, C 12 H 14 F 3 N 3 O, the perhydropyridazine ring adopts a chair conformation. The amide group and the benzene ring are coplanar. Intermolecular N-HÁ Á ÁO hydrogen bonds link the molecules into a chain along the a axis.
The title molecule, C 15 H 12 N 2 O 2 , is essentially planar. The crystal structure is stabilized by an extensive hydrogenbonded network. There are two intramolecular hydrogen bonds resulting in six-membered rings in graph-set patterns S(6) and three intermolecular interactions. Two of these are C-
In the title molecule, C~17~H~15~N~3~O, the pyrazole ring makes dihedral angles of 22.0 (2) and 66.5 (3)° with the two phenyl rings. In the crystal structure, intermolecular N—H...O and C—H...O hydrogen bonds link the molecules into ribbons running along the __a__ axis.
