چکیده
The title compound, C(10)H(12)FN(3)S, crystallizes in the same space group (P2(1)/c) as two polymorphic forms of 4-phenyl-1-(propan-2-yl-idene)thio-semicarbazone [Jian et al. (2005). Acta Cryst. E61, o653-o654; Venkatraman et al. (2005). Acta Cryst. E61, o3914-o3916]. The arrangement of mol-ecules relative to the twofold screw axes is similar to that in the crystal structure of the lower density polymorph. In the solid state, the mol-ecular conformation is stabilized by an intra-molecular N-H⋯N hydrogen bond. The mol-ecules form centrosymmetric R(2) (2)(8) dimers in the crystal through pairs of N-H⋯S hydrogen bonds.

In the title compound, C(7)H(9)ClN(4), the 3-chloro-6-hydrazinylpyridazine unit is planar (r.m.s. deviation = 0.0219 Å) and is oriented at a dihedral angle 4.66 (27)° with respect to the propan-2-yl-idene group. In the crystal, the mol-ecules are linked into non-planar dimers due to a crystallographic twofold rotation via N-H⋯N hydrogen bonds with R(2) (2)(8) graph-set ring motifs.

In the title compound, C29H32N2O2, the piperidine ring exists in a chair conformation (the bond-angle sum at the sp (2)-hybridized C atom is 359.79°). The phenyl rings and the methyl group substituted on the heterocyclic ring are in equatorial orientations. In the crystal, pairs of C-H⋯π inter-actions result in the formation of inversion dimers.
