Ni(II) and Pd(II) complexes based on <i>N</i>-((1<i>H</i>-pyrrol-2-yl)methylene)-2-(diphenylphosphino)benzenamine were synthesized and characterized. X-ray diffraction studies on complexes <b>1</b>, <b>2</b>,<b></b> and <b>4</b> revealed that N, N, P, and halogen atoms coordinated to metal, with distorted square planar geometries in all cases. Upon treatment with modified methylaluminoxane (MMAO), the [N<sup>−</sup>NP]Ni(II)X complexes are robust and exhibit high activity for the vinyl addition polymerization of norbornene (up to 5.46 × 10<sup>7</sup> g PNB/mol(Ni)·h·atm).
