Abstract

In the title compound, [Fe(2)(C(4)H(2)N(2)S(2))(C(3)H(9)P)(CO)(5)], the Fe(2)S(2) core adopts a butterfly conformation. The PMe(3) ligand is coordinated in the basal position, roughly cis to the Fe-Fe bond. The Fe-Fe distance of 2.4970 (6) Å is relatively short compared to those (ca 2.53 Å) found in another monosubstituted diiron compound. A rigid planar dithiol-ate bridge is featured, with an angle of 2.78 (1)° between the Fe-Fe bond and the normal to the pyrazine-2,3-dithiol-ate plane.

摘要

在标题化合物[Fe₂(C₄H₂N₂S₂)(C₃H₉P)(CO)₅]中，Fe₂S₂核呈蝶形构象。PMe₃配体在基面位置配位，大致与Fe - Fe键呈顺式。与另一种单取代二铁化合物中的Fe - Fe键距离（约2.53 Å）相比，该化合物中2.4970 (6) Å的Fe - Fe键距离相对较短。其特点是存在一个刚性平面二硫醇盐桥，Fe - Fe键与吡嗪 - 2,3 - 二硫醇盐平面法线之间的夹角为2.78 (1)°。
