SN2 reactions

This dataset probes chemical reactions of methyl halides with halide anions, i.e. 
X- + CH3Y -> CH3X +  Y-, and contains structures for all possible combinations of 
X,Y = F, Cl, Br, I. The dataset also includes various structures for several smaller 
molecules that can be formed in fragmentation reactions, such as CH3X, HX, CHX or 
CH2X- as well as geometries for H2, CH2, CH3+ and XY interhalogen compounds. In total, 
the dataset provides reference energies, forces, and dipole moments for 452709 structures 
calculated at the DSD-BLYP-D3(BJ)/def2-TZVP level of theory [1-4] using the ORCA 4.0.1 
code [5,6].
