Metallophilic interactions in A-frame molecules [S(MPH3)2] (MÂ =Â Cu, Ag, Au) from range-separated density-functional perturbation theory

► Range-separated DFT can describe metallophilicity. ► Metallophilicity can be captured with a range-separation parameter set to 0.4 a.u. ► Metallophilic interactions are described at the long-range MBPT2 level. ► 'Intramolecular' correlation is described by a short-range correlation functional. ► The range-separated MBPT2-DFT model performs better than regular MBPT2 and DFT.
