%X Hydrido-cod-ruthenium complexes containing hydrotris(3,5-diisopropylpyrazolyl)borate
(TpiPr) and its 4-brominated derivative (TpiPrBr), TpRRu(H)(cod), are reported. Spectroscopic
and crystallographic analyses reveal the presence of two isomeric structures, a square-pyramidal structure with a κ2-TpR ligand and an octahedral structure with an additional
3-center-2-electron Ru−H−B interaction, and isomerization from the former structure to
the latter structure is observed for the first time by means of 1H NMR analyses.
