Overall, we consider the accuracy of the DFT-D calculations to be sufficient to determine reliable parameter estimates for the intermolecular potential of our hybrid models. The agreement between our lattice energy calculations and the X23 test set and the work of Moellmann and Grimme is encouraging, as is the high accuracy of the geometry predictions across the entire reference datasets relative to experimentally-resolved structures. The energies obtained differ much more significantly when compared to experimental sublimation enthalpies, but the reliability of the experimental values are uncertain given that significant disagreements can be observed between the various sources. We find that intramolecular contributions for non-hydrogen bonding structures are generally quite small, but such contributions are much larger for structures that involve hydrogen bonds.
