Structural and magnetic conformation of a cerocene [Ce(COT′′)2]− exhibiting a uniconfigurational f1 ground state and slow-magnetic relaxation†
Abstract
Magnet-like behaviour, in the form of slow relaxation of the magnetization, was observed for a monometallic cerium(III) sandwich complex. The use of trimethylsilyl substituted COT ligands (COT′′) led to the formation of a staggered COT′′ arrangement in the cerocene-type sandwich complex with a well-defined oxidation state of +3 for the Ce ion.
