“…Recently, angular pyridinium cations and their derivatives have been successfully employed to construct a series of molecular cocrystals with a variety of organic synthons or metal complexes such as perhalometalates [ 10 , 11 , 12 ], since the cations are the hydrogen-bond donors, linking the anionic ions that act as hydrogen-bond acceptors through coordinative bonds and/or N–H ∙∙Cl–M interactions to enhance structural diversity [ 13 , 14 ]. And a series of crystal structures containing pyridinium cations and potassium tetrachloroplatinate have been cocrystallized with the hydrogen bond donor groups (N–H) through + N–H…Cl - interactions [ 15 , 16 , 17 ].…”

Three new crystal structures containing [PtCl6]2−, pyridinium and benzimidazole groups have been prepared: [PtCl6]·(H-bzm)2·2(H2O) (1), [PtCl6]·(H-bipy)2·2(H2O) (2), [PtCl6]·(H-dimethyl-bipy)2·2(H2O) (3) [H-bzm: benzimidazole cation, H-bipy: 2,2′-bipyridine cation, H-dimethyl-bipy: 4,4′-bimethyl-2,2′-bipyridine cation]. All compounds have been fully characterized by elemental analyses, single-crystal X-ray analyses, IR spectra, TG analyses, and fluorescence studies. Single-crystal X-ray diffraction analysis suggests that the primary synthon contains +N–H···Cl−, including ionic bonding and hydrogen bonding interactions. The dimensions are enhanced further by secondary O–H ∙∙Cl and N–H ∙∙O hydrogen bonding interactions between donor and acceptor atoms located at the periphery of these synthons. Moreover, coulombic attractions between the ions play an important role in reinforcing the structures of these complexes. In addition, antitumor activity against human lung adenocarcinoma cell line (A549) and human nasopharyngeal carcinoma cell line (CNE-2) was performed. These complexes all showed inhibition to the two cell lines, while complex 3 exhibited higher efficiency than complexes 1–2.
