The reaction of Os 3(CO) 10(C 2Ph 2) with PhHgCl in benzene yields [Os 3(CO) 9 (μ 3-C 2Ph 2)(μ 2-Cl)(HgCl)] 2. The complex has been characterized by the usual spectroscopic methods and by an X-ray crystal, structure determination. The compound crystallizes in the triclinic space group P 1 , cell dimensions a = 9.727(3), b = 12.590(4), c = 14.863(7) Å, α = 96.75(3), β = 109.02(3), γ = 99.58(2)°, V = 1667.8(8) Å 3, Z = 1. The three osmium atoms form a bent arrangement with the diphenyl acetylene and a chloride ion bridging the non-bonded (Os—Os distance of 3.768 Å) osmium-osmium edge, a mercury atom bridges a metal-metal bond and is also bound, in an unsymmetrical fashion to two chlorine atoms which act as bridges to an identical triosmium-mercury unit. A toluene molecule is also present in the asymmetric unit.
