Kilobytes of kilopascals: high-pressure depositions of the Cambridge Structural Database

The Cambridge Structural Database (CSD) is the largest repository of crystal structures of organic and metal–organic compounds, containing over 1.1 million entries. Over 3300 of the deposits are structures determined under high pressure, with the number being strongly affected by the experimental requirements of the high-pressure techniques. Nevertheless, it still presents a population sufficiently representative for statistical data mining. In this work, an in-depth analysis of this population is presented, showing where contributors of high-pressure depositions come from, which journals high-pressure structures are published in, and also providing information on some trends in high-pressure crystallography and how they have changed over the years elucidated from data collected in the CSD. The ultimate goal of this article is to bring the high-pressure crystallography content in the CSD to a wider audience of scientists.
