All calculations in this work were done in the ORCA quantum chemistry package (v5.0.2). The Ahlrichs-type def2-nZVPP basis sets were used with all methods. Generalized Gradient Approximation (GGA), meta-GGA and meta-NGA (Nonseparable Gradient Approximation) DFT calculations were sped up with the resolution of the identity approximation for Coulomb integrals (RI-J), while RI-J with the chain of spheres approximation for exchange integrals (RIJCOSX) was used with the hybrid and double hybrid DFAs and the Hartree-Fock steps of the Coupled Cluster calculations. The RI-C ap-proximation was used for the MP2 steps in the double hybrid DFAs, and the Coupled Cluster calculations. These also used ORCA's default frozen core settings. The various RI approximations were used with the def2/J 39 and def2-nZVPP/C 40 auxiliary basis sets and the "GridXS2" setting for RIJCOSX. All calculations were done with the default grids and self-consistentfield (SCF) convergence thresholds.
