A physico-chemical investigation of some magnetically anomalous inorganic compounds

It is suggested that the Curie Law part of the susceptibility originates mainly from non-interacting end groups and the linear sintiferromagnetic component from exchange interactions along chains of bridged copper atoms. TheoreticaJ. curves have been satisfactorily fitted to the experimental data by calculating susceptibility values from an expression derived in terms of the Ising spin model for an infinite chain of interacting copper atoms to which a proportion of Curie Law magnetic susceptibility had been added. Polymeric structures which may permit linear antiferromagnetism have been postulated for all investigated types of complexes.
