3-(Piperidin-1-yl)-6-(1H-pyrazol-1-yl)pyridazine
In the title compound, C(12)H(15)N(5), the piperidine ring adopts a chair conformation with the substituent C atom in an equatorial site and the dihedral angle between the pyridazine and pyrazole ring planes is 10.36 (2)°.
متن کامل3-Chloro-6-[2-(cyclopentylidene)hydrazin-1-yl]pyridazine
The asymmetric unit of the title compound, C(9)H(11)ClN(4), contains two virtually planar mol-ecules that differ in conformation about the bond connecting the hydrazine and pyridazine units. The 3-chloro-6-hydrazinylpyridazine and cyclo-pentane groups are oriented at dihedral angles of 4.5 (3) and 8.8 (4)° in the two mol-ecules. In the crystal, the mol-ecules form a one dimensional polymeric st...

In the title compound, C(9)H(9)ClN(4), the dihedral angle between the aromatic rings is 6.25 (9)°. The whole mol-ecule is approximately planar (r.m.s. deviation = 0.070 Å). In the crystal, π-π inter-actions between the centroids of the pyridazine rings [separation = 3.5904 (10) Å] occur.

In the title compound, C(13)H(14)ClN(5), the piperazine ring adopts a chair conformation and the dihedral angle between the aromatic rings is 13.91 (7)°. The crystal structure is stabilized by weak inter-molecular C-H⋯N hydrogen-bond inter-actions.
متن کامل3-Chloro-6-(1H-pyrazol-1-yl)pyridazine
The title compound, C(7)H(5)ClN(4), is almost planar (r.m.s. deviation = 0.022 Å). The dihedral angle between the aromatic rings is 2.82 (5)°. The packing results in polymeric chains extending along the a axis. In the crystal, mol-ecules are connected to each other through inter-molecular C-H⋯N hydrogen bonds, resulting in R(2) (2)(10) ring motifs.
