2.1 Basics of Structures


                 Determination of the ionic radius










                                                                                                  Structure analyses,

                                                                                             most important method:
                         Ionic radius = d – r(F, O…)                                                 X-ray diffraction































                    L. Pauling:



                    • Radius of one ion is fixed to a reasonable value (r(O ) = 140 pm)
                                                                                                               2-

                    • That value is used to compile a set of self consistent values for other ions.
