Summary Os2(CO)8Cl2 (1) is orthorhombic P212121 witha=9.3599(9),b=9.879(2),c=16.014(3)Å, V=1480Å3, Dc=3.03 Mgm−3 for Z=4. Structure solved by Patterson methods. Final R=0.038, Rw=0.038 [w=(σ2F)] for 1270 observed reflections and 141 parameters. Os3(CO)12Cl2 (2) is monoclinic C2/m witha=12.105(3), b=10.612(3),c=8.798(1) Å, β=117.02(2)°, V=1006Å3, Dc=3.22 Mgm−3 for Z=2. Structure solved by Patterson methods. Final R=0.036, Rw=0.037 (w=(σ2F)−) for 821 observed reflections and 75 parameters. Complex(1) has an osmium-osmium single bond 2.897(1)Å, with the chloride ligands in equatorial positions,(2) has a linear triosmium chain with osmium-osmium single bonds 2.893(1) Å and the chloride ligands occupy equatorial sites on the terminal osmium atoms. Both(1) and(2) are isostructural with their osmium carbonyl iodide analogues.
