Substantial Zr-alkyl group (R) effects on ion pair thermodynamic stability as well as on ion pair solution structure and structural dynamics are reported in the [(1,2-Me2Cp)2ZrR]+[CH3B(C 6F5)3]- series, where R = CH3, CH2C(CH3)3, CH2Si(CH3)3, and CH[Si(CH3)3]2. These quantitative results underscore the effects such R moieties are likely to play in group 4 metallocene-mediated olefin polymerization catalysis.
