xtb - An extended tight-binding semi-empirical program package can now be installed using conda

The extended tight binding program provides the geometry, frequency and non-covalent interaction (GFN) parametrisations of the tight binding Hamiltonians GFN1-xTB (JCTC 2017) and GFN2-xTB (JCTC 2019) and a preliminary version of the new GFN0-xTB All parametrisations consistently cover the entire periodic system up to Z=86 and include a continuum solvation model (GBSA) for common solvents.

conda install -c conda-forge xtb


conda install -c conda-forge/label/cf202003 xtb

The user guide is available online and the source code is on GitHub
