A Nontwisted, Ferromagnetically Coupled Mn3IIIO Triangular Complex from the Use of 2,6-Bis(hydroxymethyl)-p-cresol

The reaction between Mn(O2CMe)(2)center dot 4H(2)O and hmcH(3) [hmcH(3) = 2,6-bis(hydroxymethyl)-p-cresol] in CH2Cl2 in the presence of NEt3 affords the Mn-3(III) complex [NEt3(CH2Cl)](2)[Mn3O(hmcH)(3)(hmcH(2))(3)] (1). The anion of 1 contains a [Mn-3(III)(mu(3)-O)](7+) triangular core, with the central O2- ion lying above the Mn-3 plane. The complex is ferromagnetically coupled with a resulting S = 6 ground state.
