Reactions of aqueous HX (XCl, Br) or of AuCl(PPh 3 ) with Ru 5 (μ 5 ‐C 2 PPh 2 )(μ‐PPh 2 )(CO) 13 result in addition of the 4e‐donor set (H + X) or (Au(PPh 3 ) + Cl) with concomitant opening of two RuRu bonds to give complexes containing dimetallated triangular of ‘scorpion’ cores. Aqueous HI reacts similarly, but in this case the iodide ligand spans three Ru atoms, the (H + I) set acting as 6e‐donor. The structures of the two title compounds were confirmed by X‐ray crystallographic studies. Ru 5 (μ‐H)(μ 5 ‐C 2 PPh 2 )(μ‐PPh 2 )‐(μ‐Br)(CO) 13 is triclinic, space group P 1 , a = 9.689(2), b = 11.874(2), c = 20.005(4) Å, α = 84.66(2), β = 82.90(6), λ = 67.51(6)°, Z = 2; 6478 data with I > 2σ( I ) were refined to R = 0.0368, R w = 0.0362. Ru 5 (μ‐H)(μ 5 ‐C 2 PPh 2 )(μ 3 ‐I)(μ‐PPh 2 )‐(CO) 12 .CH 2 Cl 2 is monoclinic, space group P 2 1 / n , a = 14.809(4), b = 20.721(4), c = 17.698(5) Å, β = 111.42(2)°, Z = 4; 7815 data with I > 2σ( I ) were refined to R = 0.0440, R w = 0.0416.
