4,4'-Methyl-enebis[ N -(2-hy-droxy-3-meth-oxy-benzyl-idene)-2,6-diiso-propyl-aniline].

In the V-shaped title Schiff base, C41 H50 N2 O4 , the planes of the benzene rings of the central di-phenyl-methane unit make a dihedral angle of 70.40 (5)°, whereas the planes of the neighbouring benzene and ortho -vanilin rings are twisted with respect to one another by dihedral angles of 75.76 (5) and 73.89 (6)°. The Schiff base displays intra-molecular O-H⋯N hydrogen bonds and weak inter-molecular C-H⋯O contacts.
