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.
