The preparation and some physical properties of complexes of the types [MX3L3] where M = Re, Ru, or Os and [MX4L2] where M = Re, Os, or Ir and L = tertiary monophosphines are described. A few tertiary monoarsine analogues are also included.
描述了[MX 3 L 3 ],其中M = Re,Ru或Os和[MX 4 L 2 ],其中M = Re,Os或Ir,L =叔单膦的配合物的制备和一些物理性质。还包括一些叔单ar类似物。

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。

in [Re2Cl8]2– to yield [Re2Cl6L2] has been measured in dichloromethane solution. Only one associative reaction step is observed. Isolation of the intermediate [Re2Cl7L]– complexes allows direct measurement of a second reaction step. The kinetics of the reverse reactions has also been measured and two associative reaction steps are observed. Large ligand-labilising effects are transmitted across the
