dc.description.abstract | The derivatization of nanodiamonds (NDs) with osmium and ruthenium clusters has been carried out via the reaction of various clusters with unmodified and acid- functionalized NDs. These have been characterized by IR and mass spectrometry, as well as elemental analyses. An attempt to model the reactions with the ND surface was made using 1-adamantanecarboxylic acid. It was found that the reaction of Ru3(CO)12 (5) with 1-adamantanecarboxylic acid (AdCOOH) afforded a purple polymer [Ru2(CO)4(OOCAd)2]n (6) which dissolved reversibly in coordinating solvents (L) to form dinuclear adducts Ru2(CO)4(OOCR)2L2. The reaction of 6 with PPh3 in a 1:0.5 Ru:P ratio afforded a novel, electron deficient, tetraruthenium chain complex Ru4(CO)8(OOCAd)4(PPh3)2 (9). | |
