Coordination Of 2, 8- Bishydroxymethyl - 2, Elements Of The First Transition Series, Charles Edward O'Rear

Master's Theses

The preparation and study of 2, 8-bishydroxymethyl-2, 8-dimethyl-3, 7-diaza-1,5,9-nonanetriol with ions of the first transition series have been investigated. Spectrophotometric studies of solutions of this compound with Cu(II) and Ni(II) ions gave evidence of the formation of complexes containing one mole of ligand per metal ion throughout a wide pH range. The Cu(II) complex, the yellow colored Fe(III) complex formed at high pH, and the light blue colored Ni(II) complex have remained stable over several months. The red colored Ni(II) complex changes slowly into a more stable greenish-yellow complex. The ligand formed weaker complexes with Co(II) and Mn(II). Data from …
