[HRu6(CO)18]–: a ruthenium anion having an interstitial H-ligand. X-Ray crystal structures of two modifications
Abstract
Reaction of [Ru3(CO)12] with [Mn(CO)5]– gives [Ru6(CO)18]2– which on acidification is converted into [HRu6(CO)18]–; this monoanion has spectroscopic properties and an X-ray structure consistent with the H ligand lying at the centre of an octahedron (approximating to Oh symmetry) of ruthenium atoms.
