Crystal Lattices,of a crystal, it is thus only necessary to know the simplest repeating “motif” and the lengths and directions of the three vectors which together describe its repetition in space (Fig. 2.1). The motif can be a molecule, as in Fig. 2.1, or the building block of a network structure. Normally, it consi

There are, however, still substantial errors in these parameters, which arise partly from the approximations of the method of solution, partly from errors in evaluating the maxima in the Fourier synthesis, and partly, of course, from errors i
