  phosphorus is not coordinated to titanium in complexes 2a–c, but is coordinated to titanium in complexes 2d–f. Structures for 2c–f were further confirmed by X‐ray crystallography. Complex 2c is essentially a four‐coordinate tetrahedral geometry, whereas complexes 2d‐f adopt five‐coordinate distorted square–pyramid geometry around the titanium center. All complexes exhibited low to moderate activities toward

  phosphine-phenolate-based Cp* complexes produced high molecular weight polymers (MW > 400 000), while the Cp analogues displayed much higher activities at high temperature. Complex 3c with MMAO showed a maximum ethylene polymerization activity of 17 580 kg molZr−1 h−1 at 75 °C. In addition, the Cp based complexes 3b–e could promote ethylene and 1-hexene copolymerization with high activities.
