CA 2657157

A metal complex comprising a metal compound complexed to a heteroatomic ligand, the metal complex having Structure (X), wherein R1, R2, R3, and R4 are each independently an alkyl group, a cycloalkyl group, a substituted cycloalkyl group, an aromatic group, or a substituted aromatic group, R1c, R2c, R3c, R4c, and R5c are each independently hydrogen or an alkyl group, and MXp comprises a group IVB, VB, or VIB metal. A metal complex comprising a metal compound complexed to a diphosphino aminyl ligand comprising at least two diphosphino aminyl moieties and a linking group linking each aminyl nitrogen atom of the diphosphino aminyl moieties.

L'invention concerne un complexe métallique comprenant un composé métallique complexé à un ligand hétéroatomique, le complexe métallique ayant la Structure (X), dans laquelle R1, R2, R3 et R4 représentent chacun indépendamment un groupe alkyle, un groupe cycloalkyle, un groupe cycloalkyle substitué, un groupe aromatique ou un groupe aromatique substitué, R1c, R2c, R3c, R4c et R5c représentent chacun indépendamment l'hydrogène ou un groupe alkyle, et MXp comprend un métal des groupes IVB, VB ou VIB. L'invention concerne également un complexe métallique comprenant un composé métallique complexé à un ligand diphosphino aminyle comprenant au moins deux fractions de diphosphino aminyle et un groupe de liaison liant chaque atome d'azote aminyle des fractions de diphosphino aminyle.
