摘要：

This communication presents the crystal structures of the high spin state at 300 K, the low spin state at 30 K and the metastable high spin state after irradiation at 30 K and an estimate of the critical LIESST temperature of [FeL2]( BF4)(2) which is shown to undergo a spin transition at 271 K.
