Cp* Chemistry of main-group elements
Peter Jutzi,Guido Reumann +1 more
TL;DR: In the chemistry of main-group elements the pentamethylcyclopentadienyl (Cp*) group represents a very important substituent as discussed by the authors, and the steric requirements of the σ- or π-bound Cp* group enable the kinetic stabilization of otherwise highly reactive species.

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.

Faster data collection without loss of precision. An extension of the learnt profile method
TL;DR: In this paper, a learned and continually revised profile is fitted to X-ray diffraction step-scan measurements, previously described for protein crystals and a linear diffractometer, for a wider range of samples and a four-circle diffractometers.
