CCL:G: Best DFT functional in Gaussian 16 for Fe complexes



 Sent to CCL by: Fedor Goumans [goumans#,#scm.com]
 Dear Jonathan,
 
Here is a recent paper recommending the S12g functional: https://onlinelibrary.wiley.com/doi/10.1002/qua.26121
 
However, I don't think that's implemented in Gaussian. So you may try the BP86 functional instead, with D3 dispersion corrections.
 
You may want to think about basis sets as well! https://pubs.acs.org/doi/10.1021/jp803441m
 Hope this helps,
 Fedor

 Hi,
 I would like to try running DFT calculations for organic complexes of Fe3+.
 Can anyone recommend the best functional for this in Gaussian 16?
 Many thanks,
