Template Synthesis and Properties of Square Planar Nickel(Ⅱ) and Copper(Ⅱ) Complexes of 14-Membered Hexaaza Macrocyclic Ligands with Various Alkyl Pendant Arms at the Uncoordinated Nitrogens
Soo-Kyung Jung, Shin-Geol Kang*, Myunghyun Paik Suh
Square planar nickel(Ⅱ) and copper(Ⅱ) complexes of 14-membered macrocyclic ligands containing various alkyl pendant arms at the uncoordinated nitrogen atoms, 1,8-dipropyl, 1,8-dibutyl, 1,8-bis(2-methylpropyl), 1,8-bis(2-ethylhexyl), and 1,8-dibenzyl-1,3,6,8,10,13-hexaazacyclotetradecane have been prepared from the template condensation of ethylenediamine, formaldehyde, and appropriate primary amines in the presence of the metal ion. The spectroscopic and electrochemical properties of these complexes are similar to those of tetraaza macrocyclic complexes and are not affected significantly by the nature of the alkyl groups.
