2-[(E)-2-(Benzylideneamino)ethyl]-3′,6′-bis(diethylamino)spiro[isoindoline-1,9′-xanthen]-3-one

Abstract

In the title compound, C37H40N4O2, the xanthene and spirolactam rings are almost planar, with r.m.s. deviations from the mean planes of 0.223 (2) and 0.057 (2) Å, respectively, and form a dihedral angle of 85.76 (3)°. The dihedral angle between the xanthene mean plane and the benzene ring is 87.16 (5)°. One of the two ethyl groups of one of the diethylamino groups is disordered over two sets of sites [0.76 (1):0.24 (1)].
