Nitrilotriacetato complex

Triethanolamine complexes of chromium(iii) have been reported and characterized in i.r. spectra and thermal-decomposition studies. The chromium(iii) nitrilotriacetato-complex [CrL(H20)2] [L = N(CH2C02)3 ] complexes with thallium(iii) to give [ CrL3(0H)(H20) gTl] with a formation constant of 9 3 X 10 at 25 The hydrolysis and dimerization of [CrLlOHljV ... 

The bis(nitrilotriacetato)zirconium(IV) ion, first detected by Intorre and Martell,1 has been obtained as a hydrated potassium salt by evaporation of a solution containing zirconium oxychloride and the potassium salt of nitrilotriacetic acid. On vacuum dehydration, the anhydrous complex is formed. 

The solid-state and solution chemistry of triethanolamine complexes has been investigated. While the solid-state structure was maintained in organic solvent (38), a different structure was observed in aqueous solution.262 170 NMR spectroscopy was used to demonstrate that the two oxo groups were different and in combination with H and 13C NMR data, defined the structure as (39).262 Speciation studies and a detailed characterization of this class of compounds were important because the ligand is a commonly used buffer in biology and the complexes are model systems for interactions with proteins.61,263 The thermodynamic parameters were determined for several derivatized diethanolamine ligand-vanadium(V) complexes, and represent some of the few vanadium complexes for which such parameters are known.62 The structure of (nitrilotriacetato)dioxovanadate was reinvestigated.2 4... 

The high-pressure stopped-flow technique has been used to study the formation of the peroxo complex of (nitrilotriacetato)dioxovanadate(V). The rate law is as in equation (6) where k = 7.05 dm mol...
