Trans-effects in octahedral transition metal complexes
2000, Coordination Chemistry ReviewsCitation Excerpt :The data in Table 3 demonstrate that the strong σ-donor properties of these groups lead to considerably larger STEs than those caused by CO (30, 31, 34), Cl− (32), OH− (35) or SbPh3 (36, 37). X-ray crystal structures of the cobaloximes trans-CoIIIX(dmgH)2py (27, L=py) yield CoN(py) bond distances of 2.073(3) Å for X=CHCH2− [74] and 2.028(2) Å for X=cis-CClC(H)Cl− [75], giving a difference of ca. 0.05 Å. The η1-1,2-dichlorovinyl ligand hence exerts a rather weaker STE than its unsubstituted counterpart, which can be ascribed to a decrease in basicity caused by the electronegative chlorine atoms.
