Di-μ-di-methyl-formamide-κ4O:O-μ-tetra-hydro-furan-κ2O:O-bis--[(tetra-hydro-furan-κO)sodium(I)] bis--(μ-3,6-di-chloro-benzene-1,2-di-thiol-ato-κ3S,S′:S)bis--[(3,6-di-chloro-benzene-1,2-di-thiol-ato-κ2S,S′)iron(III)]

摘要

The title compound, [Na2(C3H7NO)2(C4H8O)5][Fe2(C6H2Cl2S2)4], was synthesized and its crystal structure was solved. The ionic crystal contains a [Fe2(S2C6H2Cl2)4]2??dimeric anion and a [Na2(THF)4(μ-THF)(μ-DMF)2]2+?cation, where THF is tetra-hydro-furan and DMF is di-methyl-formamide, comprising two sodium atoms joined by one THF and two DMF mol-ecules bridging through their O atoms. The five-coordinate environment of each Na site is completed by two terminal THF mol-ecules. The asymmetric unit contains half a cationic unit (as the cation is placed on a twofold axis) and half an anion, as there is an inversion centre at the midpoint of the Fe—Fe vectors. The cationic and anionic moieties are linked by C—H?Cl and C—H?S interactions.
