Coethite An EXAFSd and XANES study of As(lll) adsorption to a synthetic goethite suggested bidentate inner-sphere binding. One plot of As(lll) and As(V) pH adsorption envelopes. As(lll) data fitted to constant capacitance SCMf Manning, Fendorf and Goldberg (1998)... 

In contrast to the relatively simple structures incorporating one of the first three binding motifs, the polymeric complex [Cu3(5 -GMP)3(H20)8] has three distinct coordination environments about different Cu + ions. While this complex is unusually sophisticated, the polymeric nature of the material is common for many metal complexes with GMP or IMP, in which inner-sphere binding occurs to both the N-7 atom and phosphate oxygens of a single nucleotide residue, but does not involve the same metal ion. As described in Section 5.5, there are also unusual structures ( open complexes ) of Cu + species and GMP, which involve only inner-sphere metal binding to the phosphate group. 

The anti conformation preferred by the adenine residue in 5 -AMP (Figure lb) disposes this nucleotide to simultaneous inner-sphere binding of metal ions both to the phosphate oxygen and N-7 atoms. As would be expected, neither 2 -nor 3 -AMP (Figure Ic) is able to participate in forming the same type of complex for steric reasons. As was shown in experiments involving Mg +, Mn +, Cd +, Co +, and Cu +,... 

Then, the specific (inner-sphere) binding may be represented by diverse reactions for example, single-site complexation of a cation M +...
