Abstract
Structural characteristics of coordination nodes in the anticarcinogenic crystalline hydrate of the di-μ-guanine-bis-[cis-dichloroaquoplatinum(II)] dimeric complex were investigated by IR, NMR (1H,13C, and195Pt), and EXAFS methods. The guanine molecules in the keto form of the complex bridge the platinum atoms by the head-to-tail principle, and the coordination nodes are polyhedra of pentaccordinated platinum(II), PtCl2NO2, with the distances R(Pt−Cl)=2.44 Å and R(Pt−N(O))=2.06 Å. The distances from the platinum atom to the nearest atoms not chemically bonded to the metal are R(Pt−C)=2.86 Å and R(Pt−Pt)=5Å.
