Abstract

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 [Mn66-O)]18+ octahedral core. The Mn6 molecule is completely ferromagnetically coupled and possesses an S = 11 ground state, the maximum for a MnII, 2MnIII, 3MnIV species.

Graphical abstract

A new MnII/III/IV6 cluster with an octahedral topology has been obtained from the use of 1,1,1-tris(hydroxymethyl)ethane (thmeH3) in higher oxidation state Mn cluster chemistry. The complex is entirely ferromagnetically coupled, possessing the maximum possible S = 11 ground state.
