2-Hydrazino- and 2-(N1-methylhydrazino)-1,10-phenanthroline have been prepared from 2-chloro-1,10-phenanthroline and the appropriate hydrazine.These tridentate chelating agents yield bis(ligand) complexes with nickel(II) and iron(II).Spectral data for the nickel(II) complexes indicate that the field strength of the ligands is near the crossover region for iron(II).Magnetic and Moessbauer effect data indicate that a 5T21A1 spin transition occurs in salts of the complex of the methylhydrazine derivative, though a marked anion-dependence for this transition is observed.Benzaldehyde hydrazone derivatives of both hydrazines also yielded six-coordinate nickel(II) and iron(II) complexes, but these were of significantly lower field strength than the parent hydrazines.
