摘要

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, R^1c, R^2c, R^3c, R^4c, and R^5c 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.
