N′-[(5-Chloro-1H-indol-3-yl)methylene]-3,4,5-trihydroxybenzohydrazide
The two aromatic parts of the title compound, C(16)H(13)ClN(3)O(4), are connected through a conjugated -CH=N-NH-C(O)- fragment, giving an almost planar mol-ecule (r.m.s. deviation 0.08 Å). In the crystal structure, adjacent mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network.
متن کامل(Z)-2-(1-Benzyl-5-nitro-1H-indol-3-ylmethylene)-1-azabicyclo[2.2.2]octan-3-one.
In view of the biological activity associated with 1-azabicyclo[2.2.2]octan-3-ones, we have undertaken the synthesis and structural analysis of a series of 2-(substituted benzylidene/heteroaryl-3-ylmethylene)-1-azabicyclo[2.2.2]octan-3ones (Sonar et al., 2003). In order to con®rm the double-bond geometry of title compound, (I), and to obtain more detailed information on the structural conformat...

The two aromatic parts of the title mol-ecule, C(16)H(12)BrN(3)O(4), are connected through a conjugated -CH=N-NH-C(O)- fragment to furnish an almost planar mol-ecule. Adjacent mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds into a three-dimensional network. An intramolecular O-H⋯O link also occurs.

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...
متن کامل2-(6-Chloro-1H-indol-3-yl)acetonitrile
In the title compound, C(10)H(7)ClN(2), the carbonitrile group is twisted away from the plane of the indole ring system [C(cy)-C(me)-C(ar)-C(ar) = -44.7 (8)°; cy = cyanide, me = methyl-ene and ar = aromatic]. In the crystal, N-H⋯N hydrogen bonds link the mol-ecules into C(7) chains propagating in [010]. Aromatic π-π stacking inter-actions [minimum centroid-centroid separation = 3.663 (3) Å] are...
