Abstract

The precursor [Fe^III(L)Cl] (LH₂ = N,N′-bis(2′-hydroxy-benzyliden)-1,6-diamino-3-N-hexane is a high-spin (S = 5/2) complex. This precursor is combined with the bridging units [Sn^IV(X)₄] (X = CN^-, NCS^-) to yield star-shaped pentanuclear clusters, [(LFe^III-X)₄Sn]Cl₄. For X = CN^- the ⁵⁷Fe-Mössbauer data show a multiple spin transition between iron(III) in the high-spin and low-spin state, while the ^119mSn-Mössbauer data indicate a valence tautomerism between Sn(IV) and Sn(II). Changing the bridging unit from X = CN^- to X = NCS^- turns the switchability off.
