Abstract: The dinuclear title molecule, [Au₂Fe(C₁₀H₁₁N₂O₃S)₂(C₁₇H₁₄P)₂]·2CHCl₃, has crystallographic twofold symmetry with the Fe atom (bonded to two ⁵-cyclopentadienyl rings) situated on the rotation axis. The Au atom exists within a linear geometry defined by an S,P-donor set with a deviation from linearity [S-Au-P = 176.86 (6)°] due to the close approach of the thiocarbamate O atom [AuO = 3.108 (5) Å]. The molecule has a U-shaped geometry which facilitates the formation of an intramolecular AuAu interaction [3.0231 (5) Å]. In the crystal, the presence of C-HO_nitro contacts leads to the formation of layers with substantial voids; these are occupied by the solvent molecules of crystallization, which are held in place by C-HS contacts.
