N-(5-Phenyl-1H-pyrazol-3-yl)benzene-1,2-diamine

Abstract

In the title compound, C15H14N4, the phenyl and pyrazole rings are essentially coplanar, being twisted relative to each other by a dihedral of only 3.68 (11)°. The benzene ring makes a dihedral angle of 64.47 (11)° with the pyrazole ring. The crystal structure is stabilized by two inter­molecular N—H⋯N hydrogen-bonds, which build a two-dimensional network developing parallel to (100). An intra­molecular N—H⋯N hydrogen bond also occurs.

They differ from compound (Ib) in the substituents on one of the aromatic rings (see Fig.…”
