Abstract

A simultaneously protonated and functionalized silicide cluster [(NHCCu)-Cu-Dipp(eta(4)-Si-9)H](2-) was detected and characterized in liquid ammonia by NMR spectroscopy. Key NMR results were corroborated by theoretical calculations. H-1-NMR line-widths at variable temperatures revealed that proton hopping in the metalated complex [(NHCCu)-Cu-Dipp(eta(4)-Si-9)H](2-) is less pronounced than in the ...
