The "last step" is to use a plotting program to yield a nice picture of atom positions, bonding, thermal vibration ellipsoids, and packing this is an ORTEP plot (Johnson s163 Oak Ridge Thermal Ellipsoid Program) see Fig. 11.73. 

Whenever standpoints tend to diverge it often starts with semantic problems and these are to be found mostly among preparative chemists. This is so because the majority of them are pure experimentalists and consequently they believe exclusively in the truth of experiments. Therefore they do not accept that theoretical studies on molecular structures may be called structure determination because calculations do not provide an ultimate picture of a molecule. On the other hand, many experimentalists rely almost blindly on the results of X-ray structure determinations, not being aware of the fact that the nice ORTEP plots which they are keen on are derived from a model with all the restrictions a model can have. The plots are very often taken as a real display of a molecule and not that of a model. And of course, a model may be wrong, which will be demonstrated in Section IV.
