Abstract

The self-assembly of [Fe^III(Tp)(CN)₃]⁻ and [Fe^II(bik)₂(S)₂]²⁺ affords the cyanide-bridged mixed valence {Fe^III₂Fe^II₂}²⁺ molecular square, which exhibits a photomagnetic effect under laser light irradiation at low temperature and also shows thermal spin-state conversion near ambient temperature.
