[1,2-Bis(diphenyl-phosphan-yl)ethane-2κP,P']tetra-carbonyl-1κC,2κC-(µ-2-cyclo-pentyl-2-aza-propane-1,3-dithiol-ato-1:2κS,S':S,S')diiron(II)(Fe-Fe).

In the title compound, [Fe(2)(C(7)H(13)NS(2))(C(26)H(24)P(2))(CO)(4)], the Fe(2)S(2) core exhibits a butterfly-like shape, with two S atoms bridging the Fe-Fe dumbbell. Each of the two Fe atoms exhibits a distorted octa-hedral environment. One Fe atom is additionally bonded to three carbonyl C atoms, whereas the other Fe atom is additionally bonded to one carbonyl C atom and two P atoms of the chelating dppe [dppe = 1,2-bis-(diphenyl-phosphan-yl)ethane] ligand. Non-classical intra-molecular C-H⋯S hydrogen-bonding inter-actions are present in the structure. The packing of adjacent mol-ecules along [100] is accomplished mainly through van der Waals forces.
