In the title compound, C10H10N2O6·H2O, the carb-oxy-lic acid group and the nitro group are essentially coplanar with the benzene ring [maximum deviation = 0.0264 (9) Å], while the amide group is oriented at a dihedral angle of 9.22 (5)° with respect to the benzene ring. In the crystal, classical O-H⋯O and N-H⋯O hydrogen bonds and weak C-H⋯O inter-actions… (More)
In the crystal structure of the title compound, C(4)H(10)NO(2) (+)·Cl(-) (systematic name: 3-eth-oxy-3-oxopropan-1-aminium chlor-ide), there are strong inter-molecular N-H⋯Cl, C-H⋯Cl and C-H⋯O hydrogen-bonding inter-actions between the free chloride anion and the organic cation, resulting in a two-dimensional supra-molecular network in the ab plane.
In the title compound, C(8)H(11)N(3)O(4), the dihedral angle between the imidazole ring and the ethyl acetate plane is 103.1 (8)°. The crystal packing is stabilized by weak inter-molecular C-H⋯O and C-H⋯N hydrogen bonds.
The carbonyl chloride group in the title compound, C(7)H(3)ClN(2)O(5), is disordered over two orientations with occupancies of 0.505 (5) and 0.495 (5). The mol-ecule is approximately planar, the dihedral angle between the carbonyl chloride plane and benzene ring being 9.6 (4)° in the major disorder component and 7.1 (4)° in the minor component. The nitro… (More)
The title compound, C(15)H(13)NO(2), was synthesized by N-alkyl-ation of methyl bromo-acetate with 9H-carbazole. The carbazole ring system is essentially planar (mean atomic deviation = 0.0346 Å) and makes a dihedral angle of 86.5 (7)° with the methyl acetate group. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
