Abstract
Two quadridentate ligands have been prepared by reaction of 2,9-dichloro-1,10-phenanthroline with hydrazine hydrate and methylhydrazine. The formation of complexes of AgI, FeII, MnII, ZnII, CdII, HgII, and NiII with these ligands is described. Electrical conductivity, i.r., and 1H n.m.r. spectral date of diamagnetic complexes are reported. The compound 2,9-dihydrazino-1,10-phenanthroline can also act as a tridentate ligand, as in the complex with nickel perchlorate, where the metal to ligand ratio is 1 : 2. Electronic spectral data of the nickel(II) complexes are presented. The preparation of a tridentate ligand, 2-(1-methylhydrazino)-1,10-phenanthroline, and of nickel(II) and iron(II) complexes of this ligand is also reported.
