Organically templated open-framework phosphites

Abstract

Here we present a summary of the work carried out in the last few years on the synthesis and characterization of a new type of organically templated inorganic–organic solid based on the (HPO3)2−phosphite oxoanion, with special focus on the magnetostructural properties of those systems containing open d-shell transition metal ions. As a result of the inherent connectivity of the metal-phosphite framework, the magnetic behaviour of the great majority of these materials is characterized by weak antiferromagnetic interactions that become relevant only at low temperature.
