Biological recognition patterns implicated by the formation and stability of ternary metal ion complexes of low-molecular-weight formed with amino acid/peptides and nucleobases/nucleosides
TL;DR: In low-molecular-weight ternary complexes some recognition patterns are repeatedly observed as mentioned in this paper, such as long bonds between metal ions and nucleobases, hydrogen bonds between the amino group of amino acids and a carbonyl group of the nucleobas and vice versa.

(Guanidine)copper complexes: structural variety and application in bioinorganic chemistry and catalysis
TL;DR: In this paper, a review of guanidine copper compounds with an emphasis on structural characteristics and their application in bioinorganic chemistry and catalysis is presented. But the focus of this paper is on the use of the guanidines as neutral donor ligands in copper coordination.
Journal ArticleDOI
Synthesis, structure and biomimetic properties of Cu(II)-Cu(II) and Cu(II)-Zn(II) binuclear complexes: possible models for the chemistry of Cu-Zn superoxide dismutase.
TL;DR: All the observations indicate that these complexes act as good possible models for superoxide dismutase, and spectral measurements of the homobinuclear complexes have shown an antiferromagnetic exchange interaction.
