All lanthanide and actinide metals which are available as solids in sufficient quantity have undergone structural investigation at elevated pressure and can be systematically compared. Systematic comparison is much less complete for the pressure behaviour of the compounds. Sufficient information is only available for some of the 1:1 compounds with elements from the fifth and sixth main groups of the periodic table, the monopnictides and the monochalcogenides. The available information on high-pressure structures, transition pressures and compressibilities is presented. The paper centres on a comparison of the CeX compounds with ThX, on one hand, and with PuX, on the other, where the largest amount of data has been obtained.
