Bidirectional Chemo-Switching of Spin State in a Microporous Framework

The ins and outs of spin: Using the microporous coordination polymer {Fe(pz)[Pt(CN)₄]} (1, pz=pyrazine), incorporating spin-crossover subunits, two-directional magnetic chemo-switching is achieved at room temperature. In situ magnetic measurements following guest vapor injection show that most guest...

Description
Summary:	The ins and outs of spin: Using the microporous coordination polymer {Fe(pz)[Pt(CN)₄]} (1, pz=pyrazine), incorporating spin-crossover subunits, two-directional magnetic chemo-switching is achieved at room temperature. In situ magnetic measurements following guest vapor injection show that most guest molecules transform 1 from the low-spin (LS) state to the high-spin (HS) state, whereas CS₂ uniquely causes the reverse HS-to-LS transition.
