Oxidative addition of O2, Cl2, NO, NO(1+) and H2 to [Ru(η(5)-C5Me5)(Ph2PCH2CH2PPh2)](1+): X-ray structures of [Ru(Cl)2(η(5)-C5Me5)(Ph2PCH2CH2PPh2)](+) and [Ru(NO)(η(5)-C5Me5)(Ph2PCH2CH2PPh2)](2+)

Treatment of Ru(η(5)-C5Me5)(dppe)Cl (1) (dppe=Ph2PCH2CH2PPh2) with Ag(1+) (as the PF6(1-) or CF3SO3(1-) salt) in CH3NO2 as the solvent yields the 16-electron complex [Ru(η(5)-C5Me5)(dppe)](1+) (2) in quantitative yield. Complex 2 reacts with O2, Cl2, NO, NO(1+) and H2 to form the cationic Ru(IV) complexes [Ru(η(2)-O2)(η(5)-C5Me5)(dppe)](1+) (3), [Ru(Cl)2(η(5)-C5Me5)(dppe)](1+) (4), [Ru(NO)(η(5)-C5Me5)(dppe)](2+) (5) and [Ru(H)2(η(5)-C5Me5)(dppe)](1+) (6) in good yields. The crystal structures of 4b (CF3SO3(1-) salt) and 5b (CF3SO3(1-) salt) have been determined by X-ray diffraction techniques. 4b crystallizes inthe triclinic space group P1- (No. 2), with a=12.215(4), b=12.593(5), c=14.422(4)?, α=76.45(2), β=79.83(2), γ=84.64(2)°, V=2119.7(12) ?**3, Z=2. The structure was refined to R(F)=0.0418 (F 4σF). 5b crystallizes in the monoclinic space group P21/n, with a=12.679(4), b=12.269(5), c=27.658(9)?, β=90.36(1)°, V=4302(3)?**3, Z=4. The structure was refined to R(F)=0.0511(F 4σF).
