NMR Studies of a Series of Phenyl Substituted Ferric N-ethyl-N- Phenyldithiocarbamates
The proton NMR results of a series of phenyl substituted tris(N-ethyl-N-phenyldithiocarbamato)-iron(III) complexes have been successfully interpreted assuming the iron atom is in an intermediate crystal field of octahedral symmetry. The substituent in the phenyl ring has very little effect on the energy separation of the 6A 1 and 2T 2 electronic states. However, the substituent substantially influences the mthylene proton isotropic hyperfine interaction constants in the 6A 1 state. These results have been interpreted as arising from changes in the π character of the N-phenyl bond due to the degree of hindered rotation with the aromatic substitution.
