The EPR spectra of several trigonal-octahedral cobalt(I1) complexes have been used to obtain information on the *-bonding anisotropic interactions. The pattern of g values is strongly influenced by the difference between the two *-bonding parameters of individual ligands in the angular-overlap model. It was found that in Coos chromophores the larger .rr interaction is orthogonal to the Cc4-R plane. For CoN6 chromophores, where N is provided by imidazoles or bipyridine, no evidence of dominant T back-bonding was found, in agreement with previous findings.

Abstract: | The EPR spectra of several trigonal-octahedral cobalt(I1) complexes have been used to obtain information on the *-bonding anisotropic interactions. The pattern of g values is strongly influenced by the difference between the two *-bonding parameters of individual ligands in the angular-overlap model. It was found that in Coos chromophores the larger .rr interaction is orthogonal to the Cc4-R plane. For CoN6 chromophores, where N is provided by imidazoles or bipyridine, no evidence of dominant T back-bonding was found, in agreement with previous findings. |
