What is it about?
Global lattice energy searches are applied to find the lowest energy crystal structures of a binary crystalline complexes of organic molecules, considering variable composition as well as structural variables. This includes whether the two-component crystal is more stable than the pure component crystals. We find that lattice energy is a good predictor of the observed composition and structure. The results apply to both cocrystals (or co-crystals) and solvates.
Why is it important?
To our knowledge, this was the first attempt at predicting cocrystal formation for molecular systems. We studied several aspects of cocrystal stability: predicting whether cocrystal formation is favourable; the energetically most favourable composition (stoichiometry) and prediction of the crystal structure itself.
