Ethyl 3-nitro-4-(n-propylamino)benzoate
In the mol-ecule of the title compound, C(12)H(16)N(2)O(4), an intra-molecular N-H⋯O hydrogen bond results in the formation of a six-membered ring having an envelope conformation. In the crystal structure, a bifurcated intra/intermolecular N-H⋯(O,O) hydrogen bond generates inversion dimers.
متن کاملEthyl 3-nitro-4-(propylamino)benzoate
In the title compound, C(12)H(16)N(2)O(4), intra-molecular N-H⋯O and C-H⋯O hydrogen bonds generate S(6) and S(5) ring motifs, respectively. The nitro group is almost coplanar with the benzene ring, forming a dihedral angle of 6.2 (2)°. In the crystal structure, neighbouring mol-ecules are linked together by inter-molecular N-H⋯O and O⋯O inter-actions. Of interest are the short inter-molecular O...
متن کامل3-Nitro-4-(propylamino)benzonitrile
In the title compound, C(10)H(11)N(3)O(2), the nitro group is essentially coplanar with the aromatic ring [dihedral angle = 1.3 (3)°] and forms an intra-molecular amine-nitro N-H⋯O hydrogen bond. In the crystal, weak inter-molecular aromatic C-H⋯O(nitro) hydrogen bonds link the mol-ecules. Weak aromatic ring π-π inter-actions [minimum ring centroid separation = 3.7744 (13) Å] are also present.

In the title compound, C(15)H(12)ClFN(2)O(5), mol-ecules are packed in the crystal lattice in a parallel fashion sustained by various C-H⋯O [C⋯O = 3.065 (5)-3.537 (5) Å] and C-H⋯Cl [3.431 (5)-3.735 (4) Å] inter-actions.
متن کامل6-Ethyl-N-methyl-3-nitro-4-nitromethyl-4H-chromen-2-amine
In the title compound, C(13)H(15)N(3)O(5), the O and N atoms of the nitro-methyl group and the methyl C atom of the ethyl group are disordered over two sets of sites with refined occupancies of 0.629 (7):0.371 (7) and 0.533 (8):0.467 (8), respectively. The dihydro-pyran ring has an extremely flattened conformation. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, pairs of N-H⋯O hy...
