[H3Ru4(CO)12]–: the X-ray crystallographic determination of two structural isomers

Abstract

X-Ray analysis has shown the presence of two structural isomers of the [H₃Ru₄(CO)₁₂]^– anion with metal–hydrogen geometries approximating to C₂ and C_3v symmetry; although the presence of structural isomers has been postulated for several metal carbonyl hydrides, this work presents the first confirmation of their existence in the solid state.
