![]() We determined unit cells by aggregating spot-finding results into high-resolution powder diffractograms. We subjected microcrystalline suspensions to X-ray free-electron laser radiation 12, 13 and obtained thousands of randomly oriented diffraction patterns. Here we demonstrate small-molecule serial femtosecond X-ray crystallography (smSFX) for the determination of material crystal structures from microcrystals. This proliferation has led to a characterization bottleneck: many hybrid materials are obligate microcrystals with low symmetry and severe radiation sensitivity, interfering with the standard techniques of single-crystal X-ray diffraction 2, 3 and electron microdiffraction 4, 5, 6, 7, 8, 9, 10, 11. Inorganic–organic hybrid materials represent a large share of newly reported structures, owing to their simple synthetic routes and customizable properties 1.
