New bulky diphosphino‐ferrocene 4 and diphosphino‐zirconocene 8 , modified with a number of tert ‐butyl groups, were synthesized and characterized by single crystal X‐Ray and/or NMR analyses. Complex [NiCl 2 ( 4 )] was prepared and its molecular structure was established by a single crystal X‐Ray analysis. Buried percent volume (% V Bur ) of novel bulky diphosphino‐ferrocene 4 was calculated to be greater than that of dppf. Because of this [NiCl 2 ( 4 )] catalyst demonstrated 2.5 times higher activity compared to [NiCl 2 ( dppf )] in the model ethylene polymerization reaction.
