Variable temperature magnetic susceptibility and magnetization studies show that all complexes possess an S = 4 ground-state.Abstract:
The reaction of Mn(ClO4)2·6H2O with Ph-saoH2 (Ph-saoH2 = 2-hydroxybenzophenone oxime) in MeCN in the presence of sodium propionate forms the complex [MnIII6O2(Ph-sao)6(prop)2(MeCN)2]·5.27MeCN (1·5.27MeCN) (prop = propionate). Repeating the same reaction in EtOH produces the complex [MnIII6O2(Ph-sao)6(prop)2(EtOH)4] (2). Complexes 1 and 2 may be considered as structural isomers, since they display the same metallic core but different coordination modes of the propionate ligands; bridging in 1 and terminal in 2. Performing similar reactions and switching from sodium propionate to sodium adamantane-carboxylate (NaO2C-ada) and sodium pivalate (Napiv) in the presence of NEt4OH yields the complexes [MnIII6O2(Ph-sao)6(O2C-ada)2(MeOH)4] (3) and [MnIII6O2(Ph-sao)6(piv)2(EtOH)4]·0.5Et2O (4·0.5Et2O), respectively. All four complexes contain the same {MnIII3O(Ph-sao)3} building block. Variable temperature magnetic susceptibility and magnetization studies show that all complexes possess an S = 4 ground-state.read more
