Multinuclear NMR studies on solution structures and dynamics of triosmium hydrido carbonyl phosphine cluster compounds

摘要

The reaction of ($mu$-H)$sb2$Os$sb3$(CO)$sb9$(PPh$sb3$) with acetylene at room temperature provides two isomers of a hydridovinyl cluster. The solid-state structure of each isomer has been determined by single-crystal X-ray crystallography. The solution structures and dynamics have been studied by extensive $sp{13}$C NMR studies, including $sp{13}$C${sp1$H$}$ COSY and $sp{13}$C spin saturation transfer experiments.
