Semiempirical tight binding calculations, with GFN1-xTB and GFN2-xTB, were performed using the XTB program. Calculations performed using the empirically corrected B97-3c, PBEh-3c, and r 2 SCAN-3c 29 methods and DLPNO-CCSD(T 0 ) 30,31 calculations, with normalPNO criteria 32 were performed in ORCA 5.0.0. Calculations with the regular DFT functionals PW91, M06-2X, and ωB97X-D were calculated with Gaussian16. 34 Cluster configurational sampling was performed with the ABCluster program employing the CHARMM force field. Sampling using CREST 2.12 was done with GFN1-xTB (--gfn 1) in non-covalent interaction mode (--nci), and with an energy threshold of 30 kcal/mol (--ewin 30). We did a quick ABCluster calculation to generate the initial structures (lm=30, gen=30, sc=4, pop=30) and optimized the structure using GFN1-xTB before being parsed to CREST. We used the lowest energy configuration as the "good guess" and the highest energy configuration as the "bad guess". All the obtained cluster structures and thermochemistry has been added to the Atmospheric Cluster DataBase (ACDB).
