The recent integration of the domain decomposition conductor-like screening model (dd-COSMO) 167 into the xtb program package marked a significant leap in the solvation description of the xTB methods. This enhancement, especially when combined with established literature approaches for post-processing results, has greatly improved the performance of xTB methods for describing solvation-related properties. This combined approach is called the extended conductor-like polarizable continuum model (CPCM-X). It leverages a combination of methods first introduced by Klamt in the conductor-like screening model for real solvents (COSMO-RS) 168 and Marenich et al. in the universal solvation model based on solute electron density (SMD) 169 and wraps it into a convenient open-source framework, that can be easily interfaced from various software packages and methods. The native implementation of the method in the xtb software package using the GFN2-xTB method improves the solvation description for large supermolecular complexes by up to 40 % in comparison to ALPB while still being more than two orders of magnitude more efficient than DFT-based methods. It has been successfully used to develop efficient workflows for calculating solvation-based properties, such as acid dissociation constants.
