Cocrystallization of the dithiocarbamate complexes [M(S ₂CNEt ₂) ₂] (M = Ni 1, Pd 2, Pt 3) and X-substituted perfluoroarenes (X = I, Br; 1,2-dibromoperfluorobenzene FBrB and 1,2-diiodoperfluorobenzene FIB) gives isomorphous cocrystals of (1-3)·2(FBrB) and 1·2(FIB), correspondingly, whose structures were studied by single-crystal X-ray diffractometry. The crystal structures demonstrate similar intermolecular contact types: short arene MS ₄⋯π-hole stacking contacts, X⋯S halogen bonds, C-H⋯X (X = Br, I) bonds and C-H⋯F hydrogen bonds. In these structures, the {d _{z ²} -M ^IIS ₄} moiety functions as an integrated five-center acceptor (that includes a metal d _{z ²} -orbital, even for a poorly d _{z ²} -nucleophilic Ni ^II center) toward the π-hole of an X-substituted perfluoroarene. This interaction provides stacking of inorganic and organic units furnishing the reverse sandwich structures. Density functional theory (DFT) calculations, in combination with quantum theory of atoms-in-molecules (QTAIM) and noncovalent interaction plot (NCIplot) analyses, supported the structure-defining role of the {MS ₄}⋯π-hole contacts. The nucleophilicity of the {MS ₄} cores toward electron deficient π-holes was verified from the molecular electrostatic potential surface (MEP) and electron density/electrostatic potential (ED/ESP) profiles, and atoms-in-molecules (AIM) charge analysis. The relatively strong {MS ₄}⋯π-hole contact strength (interaction energies for an {MS ₄}⋯π-hole 1 : 1 adduct range from −12.1 to −13.5 kcal mol ⁻¹) is probably due to the large overlap between the electron deficient π-cloud and the integrated {MS ₄} nucleophilic core. The 1 : 1 adduct based on 3 demonstrates the largest strength (13.5 kcal mol ⁻¹) in the series and this strength agrees well with the higher d _{z ²} -nucleophilicity of the Pt ^II center revealed by the MEP analysis (−33.6 kcal mol ⁻¹).
