影响Co和Rh所在中间体排斥力大小的因素

younggood

各位大神们，我在研究Co和Rh反应性质的差别，在一篇文献中看到： We assume that the steric repulsion between the Cp* ligand and the substrate is larger with the Cp*CoIII catalyst than with the Cp*RhIII catalyst as the ionic radius of cobalt is smaller than that of rhodium (Angew. Chem.Int.Ed. 2015, 54, 12968)，请问除了Co和Rh离子半径的不同这个因素影响其排斥力大小的不同，金属的其他什么性质也会影响排斥力大小呢，不胜感激
