Voigt-Martin et al. [13] have used MICE to solve the stmcture of 4-(4 -(N,N-dimethyl)aminobenzylidene)-pyrazolidine-3,5-dione at 1.4A in projection using 42 reflections. The potential maps do not resolve atoms with these data and models have to be fitted to the map density in a way reminiscent of macromolecular crystallography. This can pose problems in structure validation which were overcome in this case by simulation calculations. There is an excellent agreement between the solution and independent model building and high resolution electron microscopy studies. 

In a similar way, Voigt-Martin et al. [14] have solved the structure of [9,9 -bianthryl]-10-carbonitrile in three dimensions using 150 unique diffraction intensities, and independently verified the result with model building and image simulation techniques. As before, the potential maps are difficult to interpret, and independent validation is an important part of the structure solving procedure.
