TLDR
The nature of the peptide seems to be a very important factor for the reactivity of copper(II) peptide complexes with bioligands as mentioned in this paper, and only four new ternary Cu(II)-complexes have been obtained.About:

TL;DR: It is concluded that direct CMP-crea interligand interactions are missing in the Cu-CMP-Crea complex due to the inappropriate correspondence between the donor and/or acceptor H-bonding properties of these ligands.

Phase annealing in SHELX-90: direct methods for larger structures
TL;DR: In this article, a phase annealing method, related to the simulated-annealing approach in other optimization problems, is proposed and it is shown that it can result in an improvement of up to an order of magnitude in the chances of solving large structures at atomic resolution.
