Abstract
BACKGROUND Due to their unique properties and potential applications in variety of areas, recently, a special attention is given to the binuclear platinum (II) complexes. They reveal a highly tunable features upon the modification of their cyclometallating and bridging ligands. OBJECTIVE The aim of this study was to evaluate the anticancer activity and DNA binding affinity of three binuclear platinum (II) complexes, including ht-[(p-FC6H4)Pt(µ-PN)(µ-NP)PtMe2](CF3CO2)(1), ht-[(p- MeC6H4)Pt(µ-PN)(μ-NP)Pt(p MeC6H4) Me] (CF3CO2)(2) and ht-[Pt2Me3(µ-PN)2](CF3CO2) (3). METHODS MTT assay was performed to study the cell viability of Jurkat and MCF-7 lines against synthesized complexes, followed by apoptosis detection experiments. Several spectroscopic methods with molecular docking simulation were also used to investigate the detail of interaction of these platinum complexes with DNA. RESULTS Cell viability assay demonstrated a notable level of cytotoxicity for the synthetic platinum complexes. Further studies proved that a pathway of cell signaling initiating the apoptosis might be activated by these complexes, particularly in the case of complexes 1 and 2. The results of both UV-visible and CD measurements showed the significant ability of these complexes to interact with DNA. While fluorescence data revealed that these complexes cannot enter DNA structure by intercalation, molecular docking assessment proved their DNA groove binding ability. CONCLUSION The remarkable apoptosis inducing activity of the binuclear platinum complexes 1 and 2 and their considerable interaction with DNA suggest them as the potential antitumor medicines.

Cooperative activation of a water molecule with a bimetallic platinum(0)–copper(i) system results in formation of copper(i) hydroxide and a platinum hydride species. The latter is stable under acidic and neutral conditions but undergoes cyclometalation in the presence of pyridine.

Abstract
The syntheses and structural characterizations of a Pt-Tl chain [{Pt(bzq)(C6F5)2}Tl(Me2CO)]n 1 and two trinuclear Pt2M clusters (NBu4)[{Pt(bzq)(C6F5)2}2Tl] 2 and [{Pt(bzq)(C6F5)2}2Pb] 3 (bzq = 7,8-benzoquinolinyl), stabilized by donor-acceptor Pt → M bonds, are reported. The one-dimensional heterometallic chain 1 is formed by alternate "Pt(bzq)(C6F5)2" and "Tl(Me2CO)" fragments, with Pt-Tl bond separations in the range of 2.961(1)-3.067(1) Å. The isoelectronic trinuclear complexes 2 (which crystallizes in three forms, namely, 2a, 2b, and 2c) and 3 present a sandwich structure in which the Tl(I) or Pb(II) is located between two "Pt(bzq)(C6F5)2" subunits. NMR studies suggest equilibria in solution implying cleavage and reformation of Pt-M bonds. The lowest-lying absorption band in the UV-vis spectra in CH2Cl2 and tetrahydrofuran (THF) of 1, associated with (1)MLCT/(1)L'LCT (1)[5dπ(Pt) → π*(bzq)]/(1)[(C6F5) → bzq], displays a blue shift in relation to the precursor, suggesting the cleavage of the chain maintaining bimetallic Pt-Tl fragments in solution, also supported by NMR spectroscopy. In 2 and 3, it shows a blue shift in THF and a red shift in CH2Cl2, supporting a more extensive cleavage of the Pt-M bonds in THF solutions than in CH2Cl2, where the trinuclear entities are predominant. The Pt-Tl chain 1 displays in solid state a bright orange-red emission ascribed to (3)MM'CT (M' = Tl). It exhibits remarkable and fast reversible vapochromic and vapoluminescent response to donor vapors (THF and Et2O), related to the coordination/decoordination of the guest molecule to the Tl(I) ion, and mechanochromic behavior, associated with the shortening of the intermetallic Pt-Tl separations in the chain induced by grinding. In frozen solutions (THF, acetone, and CH2Cl2) 1 shows interesting luminescence thermochromism with emissions strongly dependent on the solvent, concentration, and excitation wavelengths. The Pt2Tl complex 2 shows an emission close to 1, ascribed to charge transfer from the platinum fragment to the thallium [(3)(L+L')MM'CT]. 2 also shows vapoluminescent behavior in the presence of vapors of Me2CO, THF, and Et2O, although smaller and slower than those of 1. The trinuclear neutral complex Pt2Pb 3 displays a blue-shift emission band, tentatively assigned to admixture of (3)MM'CT (3)[Pt(d) → Pb(sp)] with some metal-mediated intraligand ((3)ππ/(3)ILCT) contribution. In contrast to 1 and 2, 3 does not show vapoluminescent behavior.

Abstract
The luminescent properties of cycloplatinated complexes containing aryl and SMe2 ligands, [Pt(p-MeC6H4)(ĈN)(SMe2)], (ĈN = benzo[h]quinolate (bzq), 1, or 2-phenylpyridinate (ppy), 2), were investigated in solution and solid state.
