Crystal structure of diethyl 3,3'-[(2-fluoro-phen-yl)methyl-idene]bis-(1-indole-2-carboxyl-ate). | LitMetric
In the title compound, CHFNO, the mean planes of the two indole ring systems (r.m.s. deviations = 0.1392 and 0.0115 Å) are approximately perpendicular to one another, subtending a dihedral angle of 86.0 (5)°; the benzene ring is twisted with respect to the mean planes of the two indole ring systems by 83.3 (2) and 88.1 (4)°, respectively. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further linked by N-H⋯O hydrogen bonds into supra-molecular chains propagating along the [101] direction.
