CRYSTAL AND MOLECULAR-STRUCTURE OF 3-HYDROXY-2,2'-DIOXO-[DELTA-3-3'-BIINDOLINE]-N,N'-DI(S,S-DIMETHYLSULFOXIMIDE) HYDRATE

The title compound crystallizes in space group P21/c with a = 17.988(5), b = 9.504(1), c = 14.811(4)Å, β = 106.90(2) °, Z = 4, and Dx = 1.441 g cm-3. The structure was solved by Patterson and electron density syntheses. The final R and Rw values for all reflections were 0.089 and 0.095 respectively. The molecule has an erythro configuration around C(3) and C(3′). Intramolecular distances, up to 4 Å, within the two halves of the molecule have been studied by half-normal probability methods. © 1980 Plenum Publishing Corporation.
