Magnetic Exchange in a Chloride- and Adeninium-Bridged Linear Trimer of Copper(II) -Octachlorobis(Adeninium)- Tricopper(II) Tetrahydrate

Abstract

Magnetic susceptibility measurements on a powdered sample of the linear trimer octachlorobis(adeninium)tricopper(II) have revealed exchange coupling which may be described by a pairwise Hamiltonian. The exchange integral for the coupling between adjacent copper ions is calculated to be -16.1/cm when the exchange between terminal ions in the trimer is set equal to zero. The exchange mechanism is described in terms of the orbital pathways which are available and the single ion ground state wave functions.
