Synthesis and Properties of Homonuclear Dimetallic Nickel(II), Copper(II) and Zinc(II) Complexes of p-Xylenediyl and 2-Butynediyl-Bridged Dicyclenes.

摘要

Two new dinucleating ligands have been prepared by linking two (12)-aneN4 (cyclen) macrocycles with either a p-xylenediyl or a 1,4-butanediyl bridge. The nickel (II), copper (II) and zinc (II) dinuclear complexes have been fully characterized. Their design was intended to be a mimic of the dinuclear hydrolytic enzyme urease which contains two nickel ions in the active site. Catalytic hydrolysis studies are in progress.
