Crystal structure of 2-methyl-3-nitrobenzoic anhydride
The title mol-ecule, C16H12N2O7, lies on a twofold rotation axis which bis-ects the central O atom. The dihedral angle between two symmetry-related benzene rings is 48.54 (9)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds which generate C(13) chains running parallel to [31-1].
متن کاملCrystal structure of methyl (E)-2-(1-methyl-2-oxoindolin-3-ylidene)acetate
The title compound, C12H11NO3, is essentially planar, with the mean plane of the acetate side chain [-C-C(=O)-O-C] being inclined to the mean plane of the indole ring system by 12.49 (7)°. The five- and six-membered rings of the indole group are almost coplanar, making a dihedral angle of 1.76 (8)°. The conformation about the C=C bond is E and there is an intra-molecular C-H⋯O hydrogen bond pre...
متن کاملCrystal structure of methyl (2Z)-3-(4-chlorophenyl)-2-[(3-methyl-1H-indol-1-yl)methyl]prop-2-enoate
In the title indole derivative, C20H18ClNO2, the chloro-phenyl ring is almost perpendicular to the indole moiety, making a dihedral angle of 87.6 (1)°. The mol-ecular packing is stabilized by C-H⋯π inter-actions, which form a C(9) chain motif along [10-1]. In addition, there are weak π-π inter-actions [centroid-centroid distance 3.851 (1) Å] between the chains, involving inversion-related chlor...
متن کاملCrystal structure of methyl 1-methyl-2-oxospiro[indoline-3,2′-oxirane]-3′-carboxylate
In the title compound, C12H11NO4, the dihedral angle between the indole ring system (r.m.s. deviation = 0.019 Å) and the oxirane ring is 88.8 (2)°. The oxirane O atom and the bridging ester O atom are in an approximate syn conformation [O-C-C-O = -25.4 (3)°] In the crystal, inversion dimers linked by pair of C-H⋯O hydrogen bonds generate R 2 (2)(8) loops, where the C-H donor group forms part of...
متن کاملCrystal structure of 5-(5-chloro-2-hydroxybenzoyl)-2-(2-methyl-1H-indol-3-yl)nicotinonitrile
In the title compound, C22H14ClN3O2, the indole unit is essentially coplanar, with a maximum deviation of 0.035 Å for the C atom bearing the methyl group. The central pyridine ring is inclined to the indole ring system by 43.7 (1)°. The dihedral angle between the phenyl ring and the indole ring system is 15.7 (2)°, while that between the phenyl ring and the central pyridine ring is 46.3 (1)°. T...
