Calcurmolite is a rare supergene U mineral formed during the alteration–hydration weathering of uraninite and hypo-gene Mo minerals its structure has remained unsolved owing to a lack of crystal material suitable for conventional structure analysis. Here, single-crystal precession electron-diffraction tomography shows the calcurmolite structure to be modulated. Due to the poor quality of diffraction data, only a kinematical refinement was undertaken. The structure of calcurmolite is based upon the infinite uranyl–molybdate sheets with baumoite topology and an interlayer of 6-coordinated Ca2+ cations with interstitial H2O.
