The title molecule, 2-morpholino-1,3-diphenyl-1,3-diazapropene, C17H14
N3O, contains two phenyl rings joined to a guanidine skeleton that inc
orporates a morpholine ring. The morpholine ring adopts a chair confor
mation. All substituent rings are tilted out of the guanidine plane; t
he aromatic rings are almost perpendicular to each other. Crystal cohe
sion is due to van der Waals interactions and an intermolecular N-H ..
. O hydrogen bond.
