Heat- and Light-Induced Spin Transition of an Iron(II) Polymer Containing the 1,2,4,5-Tetrakis(diphenylphosphanyl)benzene Ligand

A new iron(II) spin‐crossover compound containing a phosphane ligand has been synthesized and characterized by magnetic susceptibility, Mössbauer spectroscopy, and heat capacity and photomagnetic experiments. The [Fe(tppb)Br2] complex [tppb = 1,2,4,5‐tetrakis(diphenylphosphanyl)benzene] exhibits a g...

Description
Summary:A new iron(II) spin‐crossover compound containing a phosphane ligand has been synthesized and characterized by magnetic susceptibility, Mössbauer spectroscopy, and heat capacity and photomagnetic experiments. The [Fe(tppb)Br2] complex [tppb = 1,2,4,5‐tetrakis(diphenylphosphanyl)benzene] exhibits a gradual spin conversion at T1/2 = 184 K, and displays at low temperature a partial photoconversion of the low‐spin (LS) state into the metastable high‐spin (HS) state by irradiating the sample at 530 nm.
