PENTACOORDINATED IRON-SULFUR COMPLEXES I.SYNTHESIS AND STRUCTURE OF DINUCLEAR COMPLEX [Fe_2(o-SC_6H_4S-S,S')_4](Et_4N)_2

<正> INTRODUCTION. On close investigation of the 'P cluster' of nitrogenase, which is known to consist of Fe_4S_4~(2+) core, scientists have considered that the collective properties are highly suggestive of those being variants of analogue Fe_4S_4~(2+) clusters. Attention has been directed recently to the possibility that 'P cluster' variations may include some or all Fe atoms that are not 4-coordinated as in usual Fe-S analogues but are 5-coordinated.
