A comparison of metallophilic interactions in group 11[X-M-PH3]n (n = 2-3) complex halides (M = Cu, Ag, Au; X = Cl, Br, I) from density functional theory

Density functional calculations for metallophilic interactions in dimeric and trimeric compounds of [X-M-PH3] complexes show that three-body terms of the interaction potential are small but non-negligible compared to the total two-body term.
