Patent

CA 2646403

The invention concerns metal complexes and their preparation, in particular a metal complex MLnXm, where M is a metal of group 8, 9 or 10 and X is a halide, HCO3-, NO3-, CO32- or carboxylate. n is a number equal to or less than the coordination number of the metal and m is 1 or 2 and is equal to the oxidation state of the metal. The ligand L may be a bidentate phosphine of formula (I), (II), (III) or (IV) as set out herein. The process of production comprises reacting an ammine compound of metal M with a complexing compound, which is preferably a phosphine.

L'invention concerne des complexes métalliques et leur fabrication, en particulier un complexe métallique MLnXm, où M est un métal du groupe 8, 9 ou 10 et X est un halogénure, HCO3-, NO3-, CO33- ou un carboxylate, n est un nombre égal ou inférieur au nombre de coordination du métal et m est 1 ou 2 et est égal à l'état d'oxydation du métal. Le ligand L peut être une phosphine bidentate de la formule (I), (II), (III) ou (IV) telle que présentée ici. Le procédé de fabrication comprend la réaction d'un composé ammine du métal M avec un composé complexant, qui est, de préférence, une phosphine.
