6-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...
متن کامل6-Methoxy-N-methyl-3-nitro-4-nitromethyl-4H-chromen-2-amine
In the title compound, C(12)H(13)N(3)O(6), the dihydro-pyran ring adopts a near screw-boat conformation. The dihedral angle between the mean planes of the benzene and dihydro-pyran rings is 6.35 (5)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) motif, which stabilizes the mol-ecular conformation. In the crystal, weak inter-molecular C-H⋯O, N-H⋯O and C-H⋯π hydrogen bonds contribute ...
متن کامل2-Methyl-5-nitro-1H-benzimidazol-6-amine dihydrate
The title benzimidazole mol-ecule, C(8)H(8)N(4)O(2)·2H(2)O, is planar with a maximum deviation of 0.079 (2) Å (for one of the O atoms in the nitro group). It crystallized as a dihydrate and inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the uncoordinated water mol-ecules, and the nitro and amine groups, respectively. In the crystal, N-H⋯O, O-H⋯N, O-H⋯O and C-H⋯O hydrogen bonds link the mol...
متن کامل6,8-Dichloro-N-methyl-3-nitro-4-nitromethyl-4H-chromen-2-amine
In the title compound, C(11)H(9)Cl(2)N(3)O(5), the dihydro-pyran ring adopts a near-half-chair conformation. The benzene ring makes a torsion angle of 5.02 (5)° with the dihydro-pyran ring. Adjacent mol-ecules are inter-linked through inter-molecular C-H⋯O, N-H⋯O and C-Cl⋯π [3.4743 (9) Å] inter-actions. The inter-molecular N-H⋯O hydrogen bond generates an R(2) (2)(12) motif, which is observed t...
متن کامل4-[4-(Diethylamino)phenyl]-N-methyl-3-nitro-4H-chromen-2-amine
In the title compound, C(20)H(23)N(3)O(3), the dihydro-pyran ring adopts half-chair conformation. The chromene system makes a dihedral angle of 87.35 (5)° with the adjacent benzene ring. An intra-molecular N-H⋯O hydrogen bond generates an S(6) motif, which stabilizes the mol-ecular conformation. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds contribute to the stabilization of the pac...
