The prismane complex (Et4N)3[Fe6S6Cl6] was investigated by Mossbauer spectroscopy under various experimental conditions, i.e. at temperatures 0.3–250 K in a field of 20 mT (⊥γ), at 300, 600 and 900 mK in a field of 1 T (⊥γ), and at 4.2 and 10

Iron clusters are the catalytically active groups of many proteins. The basis building blocks of these clusters are few; they are all variants of three archetypal patterns: [Fe–O–Fe], [2Fe–2S], and [4Fe–4S]. Mossbauer spectroscopy, in conjunc

Values for the exchange-coupling constant J and the double-exchange parameter B have been estimated for dimeric and hexameric mixed-valence iron clusters. For sulfur-bridged species the range of J values is 300–450 cm–1, and B values vary between

Samples of the dithionite-reduced FeFe protein (the dinitrogenase component of the Fe-only nitrogenase) from Rhodobacter capsulatus have been investigated by Fe-57 Mossbauer spectroscopy and by Fe and Zn EXAFS as well as XANES spectroscopy. The analy

The prismane protein of Desulfovibrio vulgaris, in its isolated, its one-electron-reduced and its oxidized states, was the subject of a detailed Mossbauer investigation. Measurements were recorded in the range 0.295-77 K and in the field range 0-6.2

In addition to the Mo-dependent nitrogenase, the existence of an iron-only nitrogenase system has been demonstrated in R. capsulatus and a rapid and gentle isolation procedure yielding highly active protein components (FeFe protein and Fe protein) ha
