Abstract: Data on the ability of the important bioligands creatinine and creatine to form various types of complexes with different metal ions are summarized. The crucial role of the nature of the reaction medium in complex formation with these ligands is emphasized. The conditions for obtaining paramagnetic oligomeric platinum complexes of the “platinum blue” type (resulting from multistep redox and coordination processes) are presented.

TL;DR: In this article, the complexation ability of saturated and unsaturated N 6 macrocycles towards different metal ions, synthesis, thermodynamics and structure of the metal complexes (mono-and dinuclear) formed are discussed.
Abstract: The complexation ability of saturated and unsaturated N 6 macrocycles towards different metal ions, synthesis, thermodynamics and structure of the metal complexes (mono- and dinuclear) formed are discussed. The data concerning protonation processes of the saturated azamacrocycles, i.e. cyclic polyamines and their ability to react selectively with some anions (host-guest chemistry) are also reviewed.
