Centrosymmetric Dimers

The title compound, C6H11NO3S, provides entries to novel carbamoyl disulfanes and related compounds of interest to our laboratory. The atoms of the central O(C=S)N(C=O)O fragment have an r.m.s. deviation of 0.1077 Å from the respective least-squares plane. While several conformational orientations are conceivable, the crystal structure shows only the one in which the carbonyl and the thiocarbonyl moieties areantito each other across the central conjugated C—N—C moiety. Pairs of 2.54 Å N—H...S=C hydrogen bonds between adjacent molecules form centrosymmetric dimers in the crystal.

In the title compound, C29H25FN2O4, 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 molecules into centrosymmetric dimers, which are further linked by N—H...O hydrogen bonds into supramolecular chains propagating along the [101] direction.
