制备了由阳离子半夹心Ru（II）配合物与各种螯合配体和双（三氟甲磺酰基）酰胺阴离子（Tf 2N −）组成的盐。这些盐可以表示为[（芳烃）RuCl（L-L）][Tf 2N]（芳烃= C6 Me 5 Bu、C6 Me 6、对伞花烃、C6 H6; L-L = 2-Py-CH 2NHCMe 2 Et、2-Py-CH双键NC 6 H13、H13 C6 NHCH 2CH 2NHC 6 H13、Me 2NCH 2CH 2SC 4 H9、Me 2CN双键CHCH双键NCMe 2）。八种盐中有两种在室温下（约20 °C）是液体，而其他盐是熔点为60-130 °C的固体。从熔融态冷却后，大多数盐在−30 °C和−5 °C之间表现出玻璃化转变。发现这些盐催化环己醇的氧化，尽管在反应过程中发生分解。并测定了相关盐的晶体结构。
Salts comprising of cationic half-sandwich Ru(II) complexes with various chelating ligands and the bis(trifluoromethanesulfonyl)amide anion (Tf2N−) were prepared. These salts can be represented as [(arene)RuCl(L–L)][Tf2N] (arene = C6Me5Bu, C6Me6,p-cymene, C6H6; L–L = 2-Py-CH2NHCMe2Et, 2-Py-CHdouble bondNC6H13, H13C6NHCH2CH2NHC6H13, Me2NCH2CH2SC4H9, Me2CNdouble bondCHCHdouble bondNCMe2). Two of the eight salts are liquids at room temperature (∼20 °C), while the other salts are solids with melting points of 60–130 °C. Upon cooling from the melt, most salts exhibited glass transitions between −30 °C and −5 °C. The salts were found to catalyze the oxidation of cyclohexanol although decomposition occurred during the reaction. Crystal structures of related salts were also determined.
