Abstract

We present the results of our investigation into the effects of pressure and light on the high spin ⇆ low spin transition behavior of the dinuclear iron(II) compound [ Fe II 2 ( PMAT )2]( B F 4)4∙ DMF . It is found that increased pressure favors the stabilization of the system through a transition from the (HS-HS) state to the (HS-LS) state. Interestingly, even under the pressure of 10.3 kbar and low temperatures, there is no evidence of the (LS-LS) form. Irradiation of the (HS-LS) state with light induces a transition from (HS-LS) to a (HS-HS) metastable state. These results underline the role of intermolecular interactions in the stabilization of the dinuclear lattice system.
