Old ligands with new coordination chemistry: A Mn17Na cluster bearing triethanolamine and azide groups and exhibiting slow magnetization relaxation

Abstract

The combination of azide, carboxylate and triethanolamine ligands in higher oxidation state Mn cluster chemistry has yielded a new heptadecanuclear, mixed-valence (II, III, IV) compound with fairly large S and D values, and frequency-dependent out-of-phase (χM) signals, characteristics of the superparamagnetic-like slow relaxation of an SMM.

Graphical abstract

A new Mn17Na cage-like cluster has been observed from the amalgamation of azide, carboxylate and triethanolamine ligands in Mn cluster chemistry. The complex exhibits frequency-dependent out-of-phase tails of signals, characteristics of the superparamagnetic-like slow relaxation of an SMM.
