Structure and Magnetic Properties of Iron(II/III) Complexes with N2O22- Coordinating Schiff Base Like Ligands (Eur. J. Inorg. Chem. 4/2009)

The cover picture shows the general formula of the iron complexes presented in the Microreview by B. Weber and E.‐G. Jäger on p. 465ff with single crystals of one of the complexes in the background. The application of this system ranges over model compounds for biological systems to molecular magnets or molecular switches. The examples show the reversible binding of the biomolecule nitric oxide, a spin‐crossover complex with a 70 K wide thermal hysteresis loop around room temperature and an example for spontaneous magnetic ordering below 10 K.
