In contrast to this rather consistent picture, a previous investigation of stacking interactions in a semiinfinite two-layer model of COF-1 concluded that offsetstacking is driven by electrostatics and dispersion, with no role for Pauli repulsion. This analysis was based on results from a periodic EDA 66 applied to periodic PBE+D3/TZ2P calculations, which favor an offset of ∆x = 1.8 Å and ∆y = 3.3 Å at an interlayer separation of 3.1 Å. These offsets are at least roughly consistent with (if somewhat larger than) those predicted in the present work and in other DFT calculations, and we confirmed that PBE+D3/def2-ma-SVP calculations for the finite (COF1) 2 model that is considered here do predict a larger offset. (A two-dimensional E int surface at the counterpoise-corrected PBE+D3/def2-ma-SVP level of theory is shown in Fig. .) This indicates that the different offset as compared to the present work mostly reflects the level of theory rather than the use of a semiinfinite model in Ref. 18.
