Abstract

We present 57Fe Mössbauer spectroscopy experiments on the cyclic spin-cluster Fe6(tea)6(CH3OH)6 (tea = triethanolaminato(-3)). In former studies, the spin cluster has been treated as a homogenous, quasi-one-dimensional spin S=5/2 Heisenberg antiferromagnet. Our experiments reveal spectra, which consists of two different quadrupolar doublets. In consequence, there are two different Fe sites among the hexanuclear iron spin-cluster.
