4-(4-Chloro-phen-yl)-1-methyl-3-trifluoro-methyl-1H-pyrazol-5-amine.

ABSTRACT

The five-membered ring of the title compound, C(11)H(9)ClF(3)N(3), is almost planar (r.m.s. deviation = 0.002 Å) and the phenyl-ene ring is aligned at 44.8 (1)°. The N atom of the amino substituent shows a pyramidal geometry and is a hydrogen-bond donor to a Cl atom and to a ring N atom, which together generate a layer motif.
