Including two six-membered chelates as in (239) appears to position these in the equatorial plane,853 and a similar result is found in the crystal structure of the ethylenediaminedisuccinic acid (edds) complex (240).854 Removal of these less-strained equatorial chelates to form quinquedentate complexes (equation 142) appears to be difficult. Substitution of methyl groups on two of the acetate arms seems to force these into axial positions.855 The free acetate arms of [CoX(edta)]n (X = H20, NH3, N02 ) can coordinate to other metal ions and (241) has been prepared. [Pg.809]

The oxidation of aminopolycarboxylic acids by Ce(IV) produces numerous species which can be used to infer mechanistic pathways. A more well-defined aspect of these systems is revealed in the initial steps of this class of reactions. Prior to the oxidation steps, Ce(IV) forms complexes with these compounds as demonstrated in the studies of Trubacheva and Pechurova (1981) and Hanna and Moehlenkamp (1983). The experimental constraints in the former study with ethylenediaminedisuccinic acid as the substrate resulted in a metastable complex formulated as Ce(OH)(EDDS) with log X,lab = 16.46. The subsequent redox reaction is extremely slow and exhibits a complex hydrogen ion concentration dependence. The latter system, wherein the substrate is A -benzyliminodiacetic acid (BIDA), was described in terms of the sequential reaction ... [Pg.356]
