The crystal and molecular structure of the complex containing cobalt‐carbon and iron‐sulfur cluster cores, (μ‐ p ‐CH 3 C 6 H 4 C 2 S) (μ‐ n ‐C 3 H 7 S)Fe 2 (CO) 6 Co 2 (CO) 6 , has been determined by X‐ray diffraction method. The crystals are triclinic, space group P &1bar;, with a — 9.139(2), b =9.610(1), c ‐17.183(2) Å, α = 84.36(1), β‐89.45(1), γ=88.15(1)°, V ‐1501.0 Å 3 ; Z =2, D c =1.74 g/cm 3 . R =0.072, Rw =0.081. The results of the structure determination show a cobalt‐carbon cluster core formed through the reaction of (μ‐ p ‐CH 3 C 6 H 4 C 2 S)(μ‐ n ‐C 3 H 7 S)Fe 2 (CO) 6 with Co 2 (CO) 8 . In the cobalt‐carbon cluster core, the bond length of the original C≡C lengthened to 1.324 Å which is close to the typical value of carbon‐carbon double bond. The groups connecting the carbons of the cluster core are in cis position and lie on the opposite side of cobalt atoms. In this complex, the conformation of —SC 3 H 7 is e ‐type, while that of —SC 2 C 6 H 4 CH 3 is a ‐type.
