N-(2-Methylphenyl)-6-(1H-pyrazol-1-yl)pyridazin-3-amine
Abstract
The title compound, C14H13N5, crystallizes with two crystallographically independent molecules in the unit cell. The two molecules form dimers through intermolecular N—H...N and C—H...N hydrogen bonds. The hydrogen-bonding motifs are R22(8) for both the N—H...N and C—H...N interactions. The pyrazole and pyrimidine rings form dihedral angles of 6.2 (3) and 8.3 (3)° with each other and the dihedral angles between the pyrazole and benzene rings are 54.9 (2) and 58.6 (2)°. The benzene rings of neighbouring dimers also exhibit C—H...π interactions.
