| Abstract: | The compounds Os2(O2CCH3)4Cl2,1 and Os(O2CC2H5)4Cl2, 2, have been structurally characterized. Both compounds crystallize in space group P21/n. For 1 the unit cell parameters are a = 6.546(1) Å, b = 8.950(1) Å, c = 12.533(1) Å, β = 90.17(1)° and Z = 2; for 2 they are a = 6.792(2) Å, b = 10.519(3) Å, c = 13.372(4) Å, β = 89.27(3)° and Z = 2. Both molecules have approximate D4th symmetry with important dimensions as follows: for 1, Os≡Os 2.314(1) Å, OsCl 2.448(2) Å; for 2, Os≡Os 2.316(2) Å, OsCl 2.430(5) Å. The mass spectra of these compounds as well as that of Os2(O2CC3H7)4Cl2,3, are reported and discussed. |
