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.
                                    描述了[OsH 4 L 3 ](L =叔膦或
砷化氢)的制备方法。许多中性
配体L'(但不是二氮)会取代二氢,生成顺式-[OsH 2 L 3 L']配合物。
氢化物络合物是路易斯碱。它们也是烯烃异构化和聚合的催化剂。
