The title compound, C(12)H(28)N(6), is located about an inversion center situated at the center of the -CH(2)-CH(2)- bond. The C-N bond lengths are 1.285 (2), 1.384 (2) and 1.395 (1) Å, indicating double- and single-bond character. The N-C-N angles are 114.1 (1), 119.3 (1) and 126.5 (1)°, showing a deviation of both CN(3) planes from an ideal trigonal-planar geometry.

Antioxidants act as free radical scavengers in the oxidation processes. Thus, they will certainly play diverse roles in the biological systems and the therapy of a wide variety of diseases. Regarding this fact, in the present study, we synthesized two new salen ligand compounds by the condensation of ethylendiamine and salicylaldehyde derivatives in excellent yields.The structures of ...
