Abstract

The compound [Ce^IVMn₈^IIIO₈(O₂CMe)₁₂(H₂O)₄]·4H₂O (1·4H₂O) has been obtained from a template synthesis involving the reaction of the chain polymer {[Mn^III(OH)(O₂CMe)₂]·(MeCO₂H)·(H₂O)}n (3) with Ce(IV). Compound 1 contains a Mn₈^III loop inside which is held the Ce(IV) ion by the bridging oxide ions. Magnetization and magnetic susceptibility studies establish that 1 has an S = 16 spin ground state, the largest yet for a Mn cluster, and displays the slow magnetization relaxation and hysteresis behavior of a single-molecule magnet (SMM). It is thus the highest spin Mn SMM discovered to date.
