Mesostructured silica fibers constitute a class of highly ordered solids whose reciprocal space consists of well‐defined extended ring structures (see Figure). Their X‐ray diffraction spots cannot be described by the Bragg equation: As described here, they exhibit unusual intensity differences between symmetry‐related spots and local minima arising from the circular fiber architecture (see also cover).
