Crystal structure of [μ(2)-1,1′-bis­(di­phenyl­phos­phanyl)ferrocene-κ(2) P:P′]bis­[(pyrrolidine-1-carbo­dithioato-κS)gold(I)]

The asymmetric unit of the title compound, {(C(34)H(28)FeP(2))[Au(C(5)H(8)NS(2))](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.
