摘要:

Mossbauer and electronic spectral data are reported for a series of bis(dimethyl glyoximato) iron(II) complexes containing imidazole, pyridine and pyrazine derivatives in the axial position. The isomer shifts increase with the pKa of the N-heterocyclic ligands, and exhibit an inverse correlation with the energies of the metal-to-equatorial ligand charge-transfer transitions.
