A series of heteronuclear nickel‐iron complexes [Fe 2 (CO) 6 (μ‐SH)(μ 3 ‐S){NiCl(PPh 3 ) 2 }] ( 1 ), [Fe 2 (CO) 6 (μ‐SH)(μ 3 ‐S){NiCl(dppe)}] ( 2 ), [Fe 2 (CO) 6 (μ 3 ‐S) 2 {Ni(PPh 3 ) 2 }] ( 3 ), [Fe 2 (CO) 6 (μ 3 ‐S) 2 {Ni(dppe)}] ( 4 ) and [Fe 2 (CO) 6 (μ‐SPh)(μ 3 ‐S){NiCl(dppe)}] ( 5 ) have been prepared. The structure of 4 has been determined by X‐ray crystallography. The central metal‐sulfur core of 4 has a trigonal bipyramidal shape with a NiFe 2 base plane with two axial sulfur atoms. Each iron atom is 5‐coordinate forming a distorted square pyramid; the nickel is square planar coordinated by two sulfur atoms and two phosphorus atoms.
