The compound [CeIVMn8IIIO8(O2CMe)12(H2O)4]·4H2O (1·4H2O) has been obtained from a template synthesis involving the reaction of the chain polymer {[MnIII(OH)(O2CMe)2]·(MeCO2H)·(H2O)}n (3) with Ce(IV). Compound 1 contains a Mn8III 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. Copyright © 2003 American Chemical Society.
