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)°

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

The title Schiff base compound, C32H22N4O, was prepared by a reaction of 4,4′-diamino­diphenyl ether and 2-quinoline­carboxaldehyde. The mol­ecule consists of two 4-{N-[(E)-quinolin-2-yl­methyl­idene]amino}­phenyl units linked by an oxygen bridge. The dihedral angles between two benzene rings and between the two quinoline ring systems are 53.81 (7) and 42.56 (4)°, respectively. Inter­molecular C—H⋯N hydrogen bonding is present in the crystal structure
