Table 1 gives also BSSE corrected complexation enthalpies.
We applied the BSSE correction to our HF, B3LYP, and MP2 results.
92 with BSSE correction), slopes are close (within standard error) to unity, and intercepts are smaller (in absolute values).
On the contrary, in all cases (with or without inclusion of trimethylphosphine and with or without BSSE correction) the smaller basis set gives better correlation as indicated by the somewhat larger [R.
Application of the BSSE correction by the counterpoise method overcorrected the error and gave systematically too low complexation energies.
