Supramolecular approach by using Jahn-Teller sites to construct a {Mn13}-based coordination polymer and modify its magnetic properties.

Put a spin on it: a {Mn(13)} coordination cluster has been used as a secondary building unit for the preparation of an open-framework structure for which the magnetic properties can be modified by solution adsorption of tetracyanoquinodimethane radical anions (TCNQ·(-)). The applied supramolecular approach takes advantage of kinetically labile Jahn-Teller sites and can be generalised for the construction and post-synthetic modification of multifunctional materials.
