A networked spin
cage comprising infinite Co<sup>II</sup><sub>6</sub>L<sub>4</sub> cages
arrays (where Co = Co(NCS)<sub>2</sub> and L = 1,3,5-tri-(4-pyridyl)-verdazal
radical) is synthesized and found to exhibit tunable magnetic and
electrochemical properties via inclusion of guests. SQUID investigation
reveals the coexistence of ferromagnetic and anti-ferromagnetic interactions
between the Co(II) ion center and radical ligands. Inclusion of electron-deficient
guests (e.g., tetracyanoethylene) dramatically enhances spin concentration
and increases anti-ferromagnetic interactions due to the formation
of charge-transfer complex between the host and the guest. In addition,
introduction of electron-rich guests (e.g., tetrathiafulvalene) into
the networked spin cages doubles the capacity for binding the lithium
ions.
