TLDR
In this paper, the X-ray crystal structure analysis of ternary copper(II) complexes, where DP and DA denote dipeptides with an aromatic amino acid residue and bidentate nitrogen donor ligands, respectively, have been studied by synthetic, crystallographic, potentiometric, and spectroscopic methods.About:

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.

π–π Stacking assisted binding of aromatic amino acids by copper(II)–aromatic diimine complexes. Effects of ring substituents on ternary complex stability
TL;DR: The results indicate that the electron density of coordinated aromatic diimines influences the intensities of the stacking interactions in the Cu(DA)(AA) systems.

Introduction of a π−π Interaction at the Active Site of a Cupredoxin: Characterization of the Met16Phe Pseudoazurin Mutant†
TL;DR: The enhanced electron transfer reactivity of Met16Phe PACu is a consequence of a lower reorganization energy due to additional active site rigidity caused by the pi-pi interaction between His81 and the introduced phenyl ring.

Modeling the mononuclear, dinuclear, and trinuclear copper(I) reaction centers of copper proteins using pyridylalkylamine ligands connected to 1,3,5-triethylbenzene spacer.
TL;DR: The mononuclear copper(I) complexes showed a distorted three-coordinate T-shape structure and a trigonal planar structure, respectively, which are very close to the coordination geometry of the CuA site of PHM (peptidylglycine alpha-hydroxylating monooxygenase) and the CuB site of CcO (cytochrome c oxidase).

Zinc(II)–phenoxyl radical complexes: Dependence on complexation properties of Zn–phenolate species
TL;DR: In this paper, the Zn(II)-phenoxyl radical was found to have a 5-coordinate trigonal-bipyramidal geometry with a coordinated phenolate moiety, and the stability of the complexes was evaluated with and without 6-methyl-2-pyridylmethyl moieties.

TL;DR: The goal of this series is to pinpoint areas of chemistry where recent progress has outpaced what is covered in any available textbooks, and then seek out and persuade experts in these fields to produce relatively concise but instructive introductions to their fields.

An empirical method for correcting diffractometer data for absorption effects
N. Walker,David I. Stuart +1 more
TL;DR: In this article, a Fourier series in the polar angles of the incident and diffracted beam paths is used to model an absorption surface for the difference between the observed and calculated structure factors.
