(Z)-3',6'-Bis(diethyl-amino)-2-(4-oxopent-2-en-2-yl-amino)-spiro-[isoindoline-1,9'-xanthen]-3-one.

ABSTRACT: In the title compound, C(33)H(38)N(4)O(3), the mean planes of the 9H-xanthene unit and spiro-lactam (nine-atom) core are almost mutually perpendicular at 87.26?(6)°. Intra-molecular N-H?O and C-H?N inter-actions influence the 4-oxo-pent-2-en-2-yl-amino conformation. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules into chains along [001].
