Linear dependence of spin exchange coupling constant on bridge angle in phenoxy-bridged dinickel(II) complexes

Abstract

A magneto-structural relationship showing linear dependence of antiferromagnetic exchange coupling constant (–J) on Ni–O–Ni bridge angle as well as the intramolecular Ni ⋯ Ni distance has been obtained with a series of phenoxy-bridged macrocyclic dinickel(II) complexes with centrosymmetric structures.
