Atomically precise rhodium nanoclusters: synthesis and characterization of the heterometallic [Rh18Sn3Cl2(CO)33]4? and [Rh7Sn4Cl10(CO)14]5? carbonyl compounds

• Synthesis and characterization of new atomically precise Rh-Sn carbonyl clusters. Redox condensation reaction confirms its efficiency in growing nanoclusters. Full structural the clusters by single-crystal X-ray diffraction. Complete accordance between predicted experimental Cluster Valence Electrons. [Rh 18 Sn 3 Cl 2 (CO) 33 ] 4- represents highest nuclearity nanocluster to date. This paper presents a deepening on investigation system heterometallic More specifically, we herein report synthesis isolation 7 4 10 14 5- ( 1 ) compound nanocluster. can be obtained reacting 16 3- homometallic cluster with hydrated Sn(II) chloride, acetone; conversely, derives from previously known 12 Sn(CO) 23 precursor after controlled addition diluted sulphuric acid. Notably, only latter has retained recurrent Sn-centred icosahedral feature, while shows molecular structure based two Rh tetrahedra joint one vertex stabilized SnCl [SnCl - fragments. Both species have been characterized infrared (IR) analysis solution, diffraction Electrospray Ionization Mass Spectrometry (ESI-MS).
