Crystal structure of [μ₂-1,1′-bis(diphenylphosphanyl)ferrocene-κ² P:P′]bis[(pyrrolidine-1-carbodithioato-κS)gold(I)]

The asymmetric unit of the title compound, {(C₃₄H₂₈FeP₂)[Au(C₅H₈NS₂)]₂}, comprises half a molecule, with the full molecule being generated by the application of a centre of inversion. The independent Au^I atom is coordinated by thiolate S and phosphane P atoms that define an approximate linear geometry [S - Au - P = 169.35(3)°]. The deviation from the ideal linear is traced to the close approach of the (intramolecular) non-coordinating thione S atom [Au⋯S = 3.1538(8)Å]. Supramolecular layers parallel to (100) feature in the crystal packing, being sustained by phenyl-thione C - H⋯S interactions, with the non-coordinating thione S atom in the role of a dual acceptor. Layers stack with no specific interactions between them.
