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(2)(II)(PMAT)(2)](BF(4))(4)center dot 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.

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(2)(II)(PMAT)(2)](BF(4))(4)center dot 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.
