The reactions between trans-[OsVIO2Cl 2L2] (L = PPh3, AsPh3, SbPh 3) and carboxylic acids RCO2H (R = CH3, C(CH3)3, CH2Cl, CCl3, CF 3) are studied. The resulting binuclear compounds were found to have the general formula [Os2IV(μ-O)(μ-O 2CR)2Cl4(L)2] (L = PPh3; R = CH3, C(CH3)3, CH2Cl, CCl 3, CF3, and L = AsPh3; R = CH3, CH2Cl, CCl3, CF3). X-ray diffraction analysis revealed that the [Os2IV(μ-O)(μ-O 2CCCl3)2Cl4(PPh3) 2]·CH2Cl2 complex crystallizes in a triclnic system with space group P1 ; a = 10.747(2) A, b = 19.291(4) A, c = 24.614(5) A, α = 100.08(3)°, β = 90.63(3)°, γ = 97.05(3)°, V = 4983.5(17) A3, Z = 4. The Os(μ-O)Os angle is 142.2(7)°. The interaction of trans-[Os VIO2Cl2(SbPh3)2] with all the acids under study is attended by intramolecular redox reaction resulting in SbCl2Ph3.
