Abstract
Complexes of nickel(II) and iron(II) of co-ordination number six with respect to the new potentially terdentate ligands 4-, 5-, and 6-methyl, and 5-nitro-2-pyridyldi-(2-pyridyl)amine are reported. Electronic and Mössbauer spectral data are analysed and it is noted that the influence of the substituent, though small, is detectable. The implications of the results in terms of σ and π covalency within the complexes is qualitatively discussed as are some factors influencing the bi- or ter-dentate co-ordination of the bases.Keywords
