N-(4-Methylphenyl)-6-(pyrazol-1-yl)pyridazin-3-amine

Abstract

In the title compound, C14H13N5, the pyrazole ring is disordered over two orientations in a 0.571 (10):0.429 (10) ratio and the dihedral angle between the pyridazine ring and the benzene ring is 28.07 (10)°. In the crystal, pairs of N—H...N and C—H...N hydrogen bonds link the molecules into dimers, with the aid of a crystallographic twofold axis. The packing is consolidated by further C—H...N bonds and weak C—H...π interactions.
