and sensing [98]. It also reflects the fact that often the only comprehensive form of
characterisation for MOFs is by X-ray diffraction in the solid state as NMR techniques to not give full structural information and so a crystal structure is often a
crucial component enabling publication.
3.1.2 Effect on Model Refinement
It might be expected that, with an increase in complexity, the agreement between the
model and the experimental data would also follow the same pattern. However, the
average R-factor (R1 is discussed in this section) has not changed much over the last
10 years with an average of 5.28% up until 2009 compared to 5.12% from 2009 to
