Hydrogen bonding in C-methylated nitroanilines: a room-temperature monoclinic polymorph of 4-methyl-3-nitroaniline with Z' = 2.
The title compound, C(7)H(8)N(2)O(2), is monoclinic (space group P2(1)/n) at 295 (2) K with Z' = 2. The two types of molecule form independent C(7) chains, and the structure is related to that of the low-temperature triclinic polymorph, where Z' = 4 in P1, by a simple displacive transformation.
