The ORCA package was used for the DLPNO-CCSD(T) calculations. Equations 2 and 3 were evaluated for both basis sets, DZ and TZ. A two-point extrapolation (DZ-TZ) to the CBS limit was applied, as described in reference 56. We also computed the average of the CP and non-CP approaches as BE i ave = BE i CP + BE i non-CP /2, with i = DZ, TZ, and DZ-TZ.
