The title complex, dicarbonyl-3κ(2)C-(μ(3)-3,6-dimethyl-3,6-diaza-octane-1,8-dithiol-ato-1:2:3κ(7)S:S,N,N',S':S,S')(μ(2)-3,6-di-methyl-3,6-diaza-octane-1,8-dithiol-ato-1:2κ(5)S,N,N',S':S)-1,2-diiron(II)-3-nickel(0) [Fe(2)Ni(C(8)H(18)N(2)S(2))(2)(CO)(2)], is the second example showing M(μ-SR)(2)Ni(0)(CO)(2) coordination (M = any metal atom). Both Fe(II) ions are five-coordinated in distorted trigonal-bipyramidal geometries by two N atoms and three S atoms. The Ni atom is four-coordinated in a distorted tetra-hedral geometry by two S atoms and two carbonyl ligands. One of the 3,6-dimethyl-3,6-diaza-octane-1,8-dithiol-ate ligands is disordered, the major component having a refined occupancy of 0.873 (2). The Fe⋯Fe distance is 3.0945 (3)Å and the Ni⋯Fe distance is 2.8505 (3) Å.
标题配合物二羰基-3κ(2)C-(μ(3)-3,6-二甲基-3,6-二氮杂辛烷-1,8-二硫醇根合-1:2:3κ(7)S:S,N,N',S':S)(μ(2)-3,6-二甲基-3,6-二氮杂辛烷-1,8-二硫醇根合-1:2κ(5)S,N,N',S':S)-1,2-二铁(II)-3-镍(0)[Fe(2)Ni(C(8)H(18)N(2)S(2))(2)(CO)(2)]是显示M(μ-SR)(2)Ni(0)(CO)(2)配位（M =任何金属原子）的第二个例子。两个Fe(II)离子通过两个N原子和三个S原子以扭曲的三角双锥几何构型五配位。Ni原子通过两个S原子和两个羰基配体以扭曲的四面体几何构型四配位。3,6-二甲基-3,6-二氮杂辛烷-1,8-二硫醇根配体之一是无序的，主要组分的精修占有率为0.873 (2)。Fe⋯Fe距离为3.0945 (3)Å，Ni⋯Fe距离为2.8505 (3) Å。
