Sintesi e caratterizzazione di nuovi cluster eterometallici Rh-In

The aim of this thesis was to synthesize and to characterize new Rh-In heteroatomic carbonyl clusters. In order to achieve this goal, I investigated the reactivity between [Rh7(CO)16]3- and InCl3. The reactions were carried out with different stoichiometric ratios, testing different solvents and using both a nitrogen atmosphere and a controlled CO atmosphere. Despite the limited selectivity of these reactions, I was able to synthesize and identify five new carbonyl species: [Rh6(CO)15InCl3][NEt4]2, [{Rh6(CO)15InCl2}2][NEt4]2, [{Rh6(CO)15}2In][NEt4], [Rh12In(CO)29][NEt4]3 and [Rh12+xIny(CO)29]3-, although the latter has not been completely identified yet. The former four clusters were characterized by IR spectroscopy, ESI-MS spectrometry and single crystal X-ray diffractometry. Moreover, I performed thermal decomposition and reactivity tests on the [Rh6(CO)15InCl3][NEt4]2 cluster.
