Abstract

The topic of my thesis was focused on the synthesis of heteroatomic Rh clusters stabilized by carbonyl ligands. I studied the reactivity of [Rh7(CO)16]3- with different Sb3+ and Ge4+ salts, and tried to synthesize new species by changing the reaction conditions. Indeed, in order to obtain new Rh-Sb and Rh-Ge clusters, I employed different stoichiometric ratios, solvents and atmospheres (N2 or CO). As far as the Rh-Sb system is concerned, I successfully synthesized three new compounds through two different reactions, namely [Rh20Sb3(CO)36][NEt4]3, [Rh21Sb2(CO)38][NEt4]5 and [Rh12Sb(CO)24][NEt4]3. At the same time, I investigated the Rh-Ge system and succeeded in the isolation of the new cluster [Rh14Ge2(CO)30][NEt4]2, along with [Rh12SbGePh2(CO)26][NEt4]2, by treating [Rh7(CO)16]3- with both Ge4+ and Sb3+ salts. Each compound has been characterized by IR spectroscopy, ESI-MS spectrometry and single crystal X-ray diffractometry. Finally, I conduced chemical reactivity tests on some of the obtained compounds.
