2-[(6-Nitro-1,3-benzodioxol-5-yl)methylidene]malononitrile
In the title compound, C(11)H(5)N(3)O(4), the nitro group is rotated by 29.91 (16)° out of the plane of the adjacent aryl ring. The 1,3-benzodioxole ring is nearly planar, with a maximium deviation of 0.0562 (10) Å. The dioxolene ring adopts an envelope conformation on the O-C-O C atom. In the crystal, mol-ecules are linked via C-H⋯O inter-actions, resulting in R(2) (2)(6) and R(2) (2)(12) grap...
متن کاملMethyl (E)-2-cyano-3-(6-nitro-1,3-benzodioxol-5-yl)acrylate
In the title compound, C(12)H(8)N(2)O(6), the 1,3-benzodioxole ring system is essentially planar [maximum deviation = 0.036 (2) Å] and the nitro group is oriented at a dihedral angle of 15.4 (1)° with respect to its mean plane. In the crystal, moleucles are linked into C(8) [101] chains by C-H⋯O hydrogen bonds, and weak aromatic π-π stacking [centroid-centroid distance = 3.887 (1) Å] also occurs.
متن کاملEthyl 4-(1,3-benzodioxol-5-yl)-6-methyl-2-sulfanylidene-1,2,3,4-tetrahydropyrimidine-5-carboxylate
In the title compound, C(15)H(16)N(2)O(4)S, the dihedral angles between the planes of the benzodioxole and ester groups and the plane of the six-membered tetra-hydro-pyrimidine ring are 89.5 (1) and 20.2 (1)°, respectively. Inter-molecular N-H⋯S hydrogen bonds assemble the mol-ecules into dimers, which are further connected via N-H⋯O inter-actions into chains parallel to [010]. Weak C-H⋯S and C...
متن کامل2-(1,3-Benzodioxol-5-yl)-1H-benzimidazole
The asymmetric unit of the title compound, C14H10N2O2, contains two independent mol-ecules. In each mol-ecule, the benzodioxole ring system displays an envelope conformation, with the methyl-ene C atom located at the flap deviating by 0.081 (2) and 0.230 (2) Å from the mean plane formed by the other atoms. The dihedral angles between the benzo-imidazole ring system (all atoms) and the benzodiox...
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...
