Crystal structure solution and refinement
WebStructure refinement: some background theory and practical strategies David Watkin Chemical Crystallography Laboratory, University of Oxford, UK. Correspondence e-mail: [email protected] Most modern small-molecule refinement programs are based on similar algorithms. Details of these methods are scattered through the literature, WebThe crystal structure of copper(ii) citrate monohydrate (C 6 H 4 O 7 Cu 2 ·H 2 O) has been solved from a mixture powder diffraction pattern. Approach to indexing, structure solution and Rietveld refinement of multiphase diffraction patterns is discussed. Rietveld refinement is carried out employing free-atom refinement and rigid body refinement.
