Figure 4.25 1D Cu(II) adenine glycine polymer
compounds catalyse nucleic acid cleavage in heterogeneous conditions. This fact
suggests that such polymeric structures could serve as models of the cooperative
interaction between nucleic acid constituents and metal ions for prebiotic catalysis. 25
A monodimensional copper(II) infi nite zigzag chain polymer, with coordinated
adenine and glycine moieties is represented in Figure 4.25. In this polymer the
