Rare “Janus”-faced single-molecule magnet exhibiting intramolecular ferromagnetic interactions† †Electronic supplementary information (ESI) available: Spectroscopy data, crystallographic data and tables, and magnetism details. CCDC 1850963. For ESI and crystallographic data in CIF or other electroni

The unusual ferromagnetically coupled compound was prepared by the use of Me3SiN3 with the metal ions being exclusively bridged by end-on N3–. Th cationic molecule is a rare example of a 3d-metal cluster exhibiting a “Janus”-faced SMM behavior for the dried and wet forms.
