Spectroscopic and magnetic properties of compounds containing the hydrazinium cation as a ligand

摘要: The compounds of formula M(N2H5)2(SO4)2, with M = Mn, Fe, Co, Ni, Cu, Zn and CdII, have been investigated by means infrared spectroscopy, ligand-field magnetic susceptibility measurements, electron paramagnetic resonance spectra, Mossbauer measurements. The spectroscopic investigations indicate a distorted octahedral coordination for the metal ions. results are in agreement previous crystal structure determination Zn(N2H5)2(SO4)2. Most spectra can be interpreted simply on basis tetragonal compressed geometry. ligand N2H5+ seems to behave as normal nitrogen-donor ligand, reflected its parameters. Evidence rhombic distortions came from EPR copper manganese compounds.
