1'-Methyl-2-oxo-5'-phenyl-spiro-[indoline-3,3'-pyrrolidine]-4',4'-dicarbo-nitrile.

ABSTRACT: The title spiro-compound, C(20)H(16)N(4)O, crystallizes with four independent mol-ecules in the asymmetric unit. In all of them, the oxindole unit is planar, the r.m.s. deviations ranging from 0.07 to 0.08?Å, while the pyrrolinyl ring adopts an envelope conformation (with the N atom representing the flap). In the crystal, adjacent mol-ecules are linked by N-H?N and N-H?O hydrogen bonds.

Project description:In the title compound, C(12)H(11)N(3), the plane of the phenyl ring and the least-squares plane of the pyrrolidine ring enclose an angle of 14.30 (6)°. The intra-cyclic N atom features a nearly trigonal-planar coordination geometry due to π-inter-actions with the aromatic system. The pyrrolidine ring is present in a twist conformation for which the closest pucker descriptor is (C9)T(C8). Weak inter-molecular C-H⋯N and C-H⋯π contacts occur.
