Figure compares absolute DLPNO errors for RI-MP2/cc-pVXZ calculations (up to X = Q) using the L7 data set, to which we add the bbr complex from Ref. 47. Interaction energies computed with the DLPNO approximation are systematically less attractive than canonical values but the error decreases as the PNO thresholds are tightened, in all basis sets. MAEs behave consistently across the cc-pVXZ sequence, although cc-pVQZ results are omitted for c3gc and bbr due to hardware constraints. The latter two complexes afford the largest DLPNO errors and this is why the MAEs for RI-MP2/cc-pVQZ [Fig. )] are about 2× smaller than those for either cc-pVDZ or cc-pVTZ.
