Deskripsi
In the title compound, C22H12N6O2·2H2O, the cyclopentene ring adopts an envelope conformation, with the spiro C atom bonded to the dicyano-substituted C atom deviating by 0.437 (2) Å from the plane of the remaining four atoms in the ring. The puckering and smallest displacement asymmetry parameters for the ring are q2 = 0.275 (2) Å, ϕ = 212.4 (4)° and Δs(C2) = 2.7 (2). The dihedral angle between the two indole groups is 60.1 (1)°. The structure contains intermolecular N—H...O hydrogen bonds involving the indole groups and O—H...O and O—H...N hydrogen bonds involving the water molecules.
