2-[N-(4-{4-[(2-Hy-droxy-5-meth-oxy-benzyl-idene)amino]-benz-yl}phen-yl)carboximido-yl]-4-meth-oxy-phenol.

In the title Schiff base, C(29)H(26)N(2)O(4), the complete molecule is generated by a crystallographic twofold axis and is V-shaped. The planes of the benzene rings of the central diphenyl-methane unit make a dihedral angle of 78.11 (4)° while adjacent benzene and 5-meth-oxy-salicyl-idene rings are twisted with respect to each other by a dihedral angle of 11.84 (8)°. The Schiff base is in the enol-imino form and an intra-molecular O-H⋯N hydrogen bond is observed.
