Περίληψη:
A general method of increasing the ground-state total spin value of a
polynuclear 3d-metal complex is illustrated through selected examples
from cobalt(II) and nickel(II) cluster chemistry that involves the
dianion of the gem-diol form of di-2-pyridyl ketone and carboxylate ions
as organic ligands. The approach is based on the replacement of hydroxo
bridges, that most often propagate antiferromagnetic exchange
interactions, by the end-on azido ligand, which is a ferromagnetic
coupler. (c) 2006 Elsevier Ltd. All rights reserved.
