Tris{2-[(2-amino-benzyl-idene)amino]-ethyl}amine.

ABSTRACT: The title Schiff base, C(27)H(33)N(7), is a tripodal amine displaying C(3) symmetry, with the central tertiary N atom lying on the threefold crystallographic axis. The N-CH(2)-CH(2)-N conformation of the pendant arms is gauche [torsion angle = 76.1 (3)°], which results in a claw-like mol-ecule, with the terminal aniline groups wrapped around the symmetry axis. The lone pair of the apical N atom is clearly oriented inwards towards the cavity, and should thus be chemically inactive. The amine NH(2) substituents lie in the plane of the benzene ring to which they are bonded. With such an arrangement, one amine H atom forms an S(6) motif through a weak N-H⋯N hydrogen bond with the imine N atom, while the other is engaged in an inter-molecular N-H⋯π contact involving the benzene ring of a neighb
