Six pentafluorophenylplatinum(II) complexes containing proton acceptor atoms (F) and pyridine-like aromatic ligands able to act as proton donors have been synthesized and characterized, with emphasis on the factors that mediate their supramolecular aggregation in the solid state - hydrogen bonds and π-π interactions. The crystal structure analyses of the mononuclear complexes cis-[Pt(C6F5)2(napy)] (1), cis-[Pt(C6F5)2(CH2napy)] (3), cis-[Pt(C6F5)2(2-ammpy)] (5), and cis-[Pt(C6F5)2(2-bipym)] (6) reveal the influence of D-H...Pt and D-H...F (D = C, N) hydrogen bonding on the organization of molecules into stacks, which can be further interconnected to generate channels. The prevalence of hydrogen bonding over π-π interactions between aromatic rings in establishing the nature of the observed supramolecular aggregation is demonstrated.
