Master's Theses
Spectrophotometric studies or solutions or 2,2;8;a. tetrakis(hydroxymethyl)-3, 7-diaza-1,5.9-nonanetriol, (HOCH2),3CHNCH2CH(OH)CH2NHC(CH2OH)3, with cobalt (II) gave evidence of complexes having metal-ligand ratios of 1:2 and 1:3. Complexation appeared nearly complete at pH 8 or greater. Between pH 8 and pH 11, the positions of the maxima in the absorbance spectra remained essentially constant and no precipitation was observed. The 1:2 complex formed rapidly, while the 1:3 complex formed more slowly, requiring one to two weeks to reach equilibrium, after which the solutions remained unchanged over a period or several months.
