Cobalt(I) complexes are relatively rare compared to Co(II) and Co(0), but the complexes CoX(PPh3)3 (X = Cl, Br, I) are known with approximate tetrahedral coordination geometry about the high spin d8 metal center. The angular overlap model was used to analyze the electronic structure of CoCl(PPh3)3 , where three independent molecules (with very similar yet statistically different bond lengths and angles) were observed in the unit cell (J. Krzystek, A. Ozarowski, S. A. Zvyagin, J. Tesler, Inorg. Chem. , 2012 , 51 , 4954). Using the angular overlap parameters for molecule 1 in Table 3 of this reference, generate an energy-level diagram for CoCl(PPh3)3 . Does the electronic structure predicted by this method surprise you? Explain. On the basis of Table 3, the chloride ligands are better π donors, and the triphenylphosphine ligands better s donors in NiCl2(PPh3)2 relative to CoCl(PPh3)3 . What is probably the most important factor that causes these differences?
