To reduce the DLPNO error for (C 96 H 24 ) 2 below 10 kcal/mol requires thresholds of normal-MP2 quality or tighter. Even then, the error for (C 54 H 18 ) 2 remains on the order of several kcal/mol and it is that large for (C 96 H 24 ) 2 even with tight-MP2 thresholds. Absent extrapolation (which is considered next), the DLPNO approximation does not afford benchmark-quality results in systems of this size.
