CNR- Istituto di Cristallografia – Bari - Italy. To solve a crystal structure, i.e. to obtain the atomic coordinates, different methods are available. . We’ll focus our attention on Direct Methods, very popular and effective, able to give in a short time and in automatic way the solution to our problem: to compute the phases lost during the diffraction experiment (the so called .
