Abstract: A new crystal form of 2-methyl-6-nitroaniline, C7H8N2O2, crystallizing with Z' = 2 in the space group P21/c, has been identified during screening for salts and cocrystals. The different N-H
O hydrogen-bonding synthons result in linear V-shaped chains in the new polymorph, rather than the helical chain arrangement seen in the known form where Z' = 1. The presence of a second component during crystallization appears to have determined the resultant crystal form of 2-methyl-6-nitroaniline.
Formula: Two polymorphs of C7H8N2O2
