The Influence of Diamagnetic Substrates Absorption on Magnetic Properties of Porous Coordination Polymers

Reported cases of the influence of guest molecules absorption/desorption on magnetic properties of porous coordination polymers (PCP) of transition metals are reviewed. Interaction of PCPs with guest molecules can modify magnetic susceptibility in wide temperature range, as well as can lead to change of the magnetic ordering or spin-crossover temperature and other magnetic characteristics. The reasons of such influence can be divided into several groups – guest molecule coordination to metal ion or decoordination; formation or cleavage of bonds in the group, which transmits exchange interactions between metal ions; or change of bond lengths or angles in coordination polymer because of crystal lattice adaptation to the guest molecule.
