Ethyl 4-(tert-butylamino)-3-nitrobenzoate
In the title compound, C(13)H(18)N(2)O(4), intramolecular N—H⋯O, N—H⋯N and C—H⋯O (× 3) hydrogen bonds generate S(6) and S(5) ring motifs. There are two crystallographically independent molecules (A and B) in the asymmetric unit. The nitro group is coplanar with the benzene ring, with O—N—C—C torsi...

Sumario: | In the title compound, C(13)H(18)N(2)O(4), intramolecular N—H⋯O, N—H⋯N and C—H⋯O (× 3) hydrogen bonds generate S(6) and S(5) ring motifs. There are two crystallographically independent molecules (A and B) in the asymmetric unit. The nitro group is coplanar with the benzene ring, with O—N—C—C torsion angles of −0.33 (13) and 0.93 (14)° in molecules A and B, respectively. In the crystal structure, neighbouring molecules are linked together by intermolecular C—H⋯O hydrogen bonds. In addition, the crystal structure is stabilized by π–π interactions with centroid–centroid distances ranging from 3.7853 (6) to 3.8625 (6) Å. |
