Cover Feature: Observation of the First Spin Crossover in an Iron(II) Complex with an S6 Coordination Environment: Tris[bis(N,N‐diethylamino)carbeniumdithiocarboxylato]iron(II) Hexafluorophosphate (Chem. Eur. J. 68/2018)

Abstract

The spin cross-over behavior of iron(II) complexes with an S6 coordination sphere (zwitterionic sulfur donor bidentate ligand) was observed for the first time. A large decrease in the volume of the formula unit (78.1 Å3) may be responsible for the large activation barrier, resulting in a slow phase transition from the high-spin state to the low-spin state. More information can be found in the Full Paper by T. Sugaya, A. Nagasawa et al. on page 17955.
