The molecule ( p,p )‐HSC 6 H 4 C≡CC 6 H 4 C≡CC 6 H 5 has been attached to a triosmium cluster and characterized crystallographically. The complex Os 3 (CO) 10 (μ‐H)(μ‐SC 6 H 4 C≡CC 6 H 4 C≡CC 6 H 5 ) ( 1 ) was obtained in 49% yield from the reaction of the thiol HSC 6 H 4 C≡CC 6 H 4 C≡CC 6 H 5 with Os 3 (CO) 10 (NCMe) 2 . The sulfur atom bridges two metal atoms on the edge of a triangular cluster of three osmium atoms. The three aryl rings are nearly coplanar. The ligand is 18.27(2) Å in length from the sulfur atom to the para ‐carbon atom of the third aryl ring. This compound may serve as a model for the coordination of thiol‐terminated molecular wires to metallic probe surfaces.
