Template Synthesis and Crystal Structure of a Novel Mononuclear Nickel(II) Complex with a Face-to-Face Bis(macrocyclic) Ligand

Abstract

A novel mononuclear nickel(II) complex of the face-to-face bis(macrocyclic) ligand depicted, in which two fully saturated 10-membered tetraaza macrocyclic subunits are linked together by two ethylene chains, was prepared by the one-pot reaction of tris(2-aminoethyl)amine and formaldehyde in the presence of the metal ion. The complex [Ni(1)](ClO4)2 has tetragonally distorted octahedral coordination geometry.
