摘要
The reaction of [Mn3O(OAc)(6)(py)(3)] with 1,1,1- tris(hydroxymethyl) ethane (H(3)thme) gives the Mn(IV)(3)Mn(III)(4)Mn(II)(2) complex [Mn9O7(OAc)(11)(thme)(py)(3)(H2O)(2)], which has an S = 17/2 ground state and displays strong out-of-phase signals in ac susceptibility studies that establish it as a new class of single-molecule magnet.
