Hydrido-complexes of osmium(II) and osmium(IV)
Abstract
The preparations of [OsH4L3](L = tertiary phosphine or arsine) are described. Many neutral ligands L′(but not dinitrogen) will displace dihydrogen yielding complexes cis-[OsH2L3L′]. The hydrido-complexes are Lewis bases. They are also catalysts for olefin isomerisation and polymerization.
