All of the known crystal structures were successfully identified in the FIT+DMA landscapes of the ten molecules, with the exception of the monoclinic form of 3,4-cyclobutylfuran. This molecule featured in the first blind test of crystal structure prediction and is known to present difficulties for force field methods. Optimizing the experimental crystal structure from the CSD using FIT+DMA leads to a large structural change when using the DFToptimized molecular geometry, where only 11 out of 30 molecules are found to match when comparing the optimized and experimental structures using the crystal structure comparison tool in Mercury . Using a similar force field 88 , Price et al. found that this polymorph was sensitive to the position of the hydrogen atom interaction site, finding a RMSD of 5.9 to 6.6% in lattice parameters when comparing the experimental structure to their optimized version . The experimental crystal structure is reproduced more satisfactorily when optimized with FIT+DMA using the experimental molecular geometry. However, to be consistent with the methodology used for all other molecules, we do not consider this polymorph further in the current study. The results for monoclinic 3,4-cyclobutylfuran highlight a limitation of the single-point energy correction approach, which relies on the force field to produce accurate structures. Thus, we plan to implement geometry optimization on the dimer-corrected lattice energy surface in future work.
