Crystal structures of the materials listed in Table. 1 of "High-throughput discovery of high-temperature conventional superconductors", generated using ab initio random structure searching (AIRSS). These are the structures as found to exhibit high-Tc superconductivity after an initial geometry optimization at the listed pressure. They are provided in the CASTEP .cell format and can be easily converted to a number of different formats using the C2x software (https://www.c2x.org.uk/).
