G. Ferguson et al., Hydrogen bonding in C-methylated nitroanilines: the three-dimensional framework structure of 2-methyl-4-nitroaniline, ACT CRYST C, 57, 2001, pp. 315-316
Molecules of 2-methyl-4-nitroaniline, C7H8N2O2, act as double donors and as
double acceptors of N-H . . .O hydrogen bonds [N . . .O 3.117 (3) and 3.23
9 (3) Angstrom; N-H . . .O 169 and 136 degrees]. The molecules are thereby
linked into a three-dimensional framework.
