title: 5-Methyl-N-[2-nitro-4-(trifluoromethyl)phenyl]-1H-pyrazole-3-amine: a chain of hydrogen-bonded R(2)(2)(6) and R(2)(2)(16) rings.
abstract: The molecular skeleton of the title compound, C(11)H(9)F(3)N(4)O(2), is almost planar and exhibits a polarized (charge-separated) electronic structure in the nitroaniline portion. Molecules are linked by N-H···N and C-H···O hydrogen bonds to form a chain in which centrosymmetric R(2)(2)(6) and R(2)(2)(16) rings alternate.
