[2-Formyl-4-methyl-6-({2-[2-(4-nitrobenzylamino)ethylamino]ethylimino}methyl)phenolato]nickel(II) perchlorate

Abstract

In the unsymmetrical title complex, [Ni(C20H23N4O4)]ClO4, the coordination geometry for the NiII atom can be described as square planar. The aromatic rings in the two ligands are almost vertical, with a dihedral angle of 85.3°. In the crystal, cations and anions are linked by weak C(N)—H⋯O hydrogen bonding.
