Nucleobases metal complexes, conformational

The evaluations presented in this section are carried out in part in a manner analogous to our previous review on Ni -nucleotide complexes [40] of course, concentrating now on Cd " which was not a part of the previous account. As is well known, nucleotides exist in solution mainly in the so-called anti conformation. Two such examples are shown in Figure 10 [11-14,50]. It is the phosphate residue in nucleotides which determines to a very large part the stability of the complexes formed with labile metal ions including Cd " [74,117,119,130] independent of the kind of nucleobase involved or whether a nucleoside mono-, di-, or triphosphate is considered.
