Previously such algorithms have been known only in several cases. The central idea of our approach is to represent a symmetric Fourier transform as a series of transforms on grids with no special points. Such transforms are reduced to P1 FFTs in one step. We provide recipes for recursive decomposition for all symmetry groups and grids. Copyright (c) 2007 International Union of Crystallography urn:issn:0108-7673 A. Kudlicki, M. Rowicka and Z.

The Rietveld refinement of the X-ray powder pattern of -quinacridone with the crystal structure of -quinacridone gives a good fit, and a reasonable looking crystal structure. However, the lattice parameters, molecular conformation and packing are wrong. This example shows that a successful Rietveld refinement is not always final proof of the correctness of a crystal structure.

TBPY-5-34-(Butane-1,4-diyl)(2-{[1-(2-oxidophenyl)ethylidene-O]amino-N}ethanolato-O)silicon, C14H19NO2Si, crystallizes in two modifications. The monoclinic form, (IIm), was obtained by crystallization over a period of 2 days at room temperature; the orthorhombic form, (IIo), crystallized overnight at 248 K. According to thermal analysis it was concluded that (IIm) is the thermodynamically stable modification and (IIo) is a kinetically formed modification.

The phase information of the diffraction pattern is embedded in a sufficiently sampled coherent diffraction pattern. Applying advanced computational methods based on iterative algorithms this diffraction pattern can be inverted to produce an image of a sample with diffraction-limited resolution. It is natural and highly attractive to use fully coherent X-ray beams produced by X-ray free-electron lasers (XFELs) for imaging nanoscale materials, magnetic domains and biological samples.
