4,4′-Methylenebis{N-[(E)-quinolin-2-ylmethylidene]aniline}

The title compound, C33H24N4, was prepared by the reaction of a bifunctional aromatic diamine (4,4′-diaminodiphenylmethane) and an aldehyde (quinoline-2-carboxaldhyde). The molecule consists of two nearly planar (or r.m.s. deviation = 0.017 Å) 4-methyl-N-[(E)-quinolin-2-ylmethylidene]aniline moieties, which are linked by the methylene group. The angle between the mean planes of the two benzene rings connected to the methylene group is 77.86 (11)°.
