摘要
The employment of 1,1,1-tris(hydroxymethyl)ethane ligand in higher oxidation state Mn cluster chemistry has yielded a new hexanuclear, mixed-valence (II,III,IV) compound with a rare [Mn-6(mu(6)-O)](18+) octahedral core. The Mn6 molecule is completely ferromagnetically coupled and possesses an S = 11 ground state, the maximum for a Mn-II, 2Mn(III), 3Mn(IV) species. (C)2008 Elsevier Ltd. All rights reserved.
