The Crystal Structure of Dehydrated Dypingite Dataset comprises comprehensive experimental data supporting the first structural characterization of dehydrated dypingite (Mg5(CO3)4.5(2)(OH)0.96(3)·5.0(2)H2O), a hydrated magnesium carbonate hydroxide mineral that remained structurally unknown for over five decades due to aggregated morphology and structural disorder. The dataset provides systematic experimental evidence demonstrating that ambient humidity significantly influences dypingite's structural properties: high humidity (80% RH) causes inhomogeneous unit cell expansion along the c-axis with long-range lattice disorder, while low humidity (20% RH) yields reduced disorder and shorter lattice parameters, with samples differing by one water molecule of hydration. The dataset includes: 1) synchrotron powder X-ray diffraction patterns of hydrated and dehydrated dypingite samples (both synthetic and mineral); 2) time-resolved dehydration data; 3) results of thermogravimetric analysis of hydrated and dehydrated synthetic dypingite; 4) refined crystal structure of dehydrated dypingite. By making these data publicly available, we hope to spark researchers’ interest in dypingite, paving the way for broader utilization of this eco-friendly material in everyday life.
