The behaviour of [RuClCp(mPTA) 2 ](OSO 2 CF 3 ) 2 ( 1 ) in water solution vs . the pH was studied. Complex 1 is stable in neutral and acidic water solution while in basic water solution another complex, [RuCp(OH-κO)(mPTA) 2 ](OSO 2 CF 3 ) 2 ·(C 4 H 10 O) ( 2 ), is obtained. Complexes [RuCp(mPTA) 2 (L)]·X n (L = H 2 O-κ O , X = − OSO 2 CF 3, n = 3 ( 3 ); L = Cl, X = BF 4 - , n = 2 ( 4 ); L = DMSO-κ S , X = − OSO 2 CF 3 , n = 3 ( 5 )) were also obtained. All presented complexes were characterised by IR and multinuclear ( 1 H, 13 C{ 1 H}, 19 F{ 1 H}and 31 P{ 1 H}) NMR spectroscopy. Improved synthesis for 1 , the thermal analysis of complexes 1 – 3 and the crystal structure of the complexes 1 and 5 are also presented. |
