Experimental Crystal data

R factor = 0.037; wR factor = 0.131; data-to-parameter ratio = 18.0. In the title compound, C16H16N2, the dihydropyrazole ring adopts a shallow envelope conformation, with the C atom bearing the phenyl group displaced by 0.298 (2) A ̊ from the other atoms (r.m.s. deviation = 0.015 Å). The dihedral angles between the four near coplanar atoms of the central ring and the N- and C-bonded phenyl groups are 13.49 (13) and 82.22 (16), respectively.
