Dinuclear dichloro complexes [Ru(C6H6)Cl 2]2, [Ru(p-MeC6H4 iPr)Cl2]2, [Ru(1,2,4,5-C6H 2Me4)Cl2]2, and [Ru(C 6Me6)Cl2]2 react in ethanol with p-bromothiophenol to give the corresponding cationic complexes [Ru 2(C6H6)2(p-S-C6H 4-Br)3]+ (1), [Ru2(p-MeC 6H4iPr)2(p-S-C6H 4-Br)3]+ (2), [Ru2(1,2,4,5-C 6H2Me4)2(p-S-C6H 4-Br)3]+ (3), and [Ru2(C 6Me6)2(p-S-C6H4-Br) 3]+ (4), which can be isolated in quantitative yield as their chloride salts. X-ray structure analysis of these complexes shows that the nature of the arene ligand influences the folding of the p-S-C 6H4-Br units. In 1, where the less hindered arene ligand is present, the three phenyl rings of the thiolato units are not constrained to a coplanar arrangement, whereas in 4 the C6Me6 forces the three phenyl rings to be in perfect planarity. Complexes 2 and 3 show an intermediary arrangement.

Efficacy of the ferrocene appended piano-stool dipyrrinato complexes [(eta6-C6H6)RuCl(fcdpm)] (1), [(eta6-C10H14)RuCl(fcdpm)] (2), [(eta6-C12H18)RuCl(fcdpm)] (3) [(eta5-C5Me5)RhCl(fcdpm)] (4) and [(eta5-C5Me5)IrCl(fcdpm)] (5) [fcdpm = 5-ferrocenyldipyrromethene] toward anticancer activity have been described. Binding of the complexes with calf thymus DNA (CT-DNA) and BSA (bovine serum albumin) have been thoroughly investigated by UV-Vis and fluorescence spectroscopy. Binding constants for 1-5 (range, 104-105 M-1) validated their efficient binding with CT-DNA. Molecular docking studies revealed interaction through minor groove of the DNA, on the other hand these also interact through hydrophobic residues of the protein, particularly cavity in the subdomain IIA. In vitro anticancer activity have been scrutinized by MTT assay, acridine orange/ethidium bromide (AO/EtBr) fluorescence staining, and DNA ladder (fragmentation) assay against Dalton’s Lymphoma (DL) cells. Present study revealed that rhodium complex (4) is more effective relative to ruthenium (1-3) and iridium (5) complexes.

Hetero-bimetallic polyhydride clusters exhibit a regio- and chemoselective activation of a substrate. The rational synthetic method for hetero-bimetallic polyhydride complexes using readily available halide complexes is reported. The reaction of hetero-bimetallic Ru-Ir trichloride complex, Cp?Ru(mu-Cl)3IrCp?(5a), in 2-propanol in the presence of a base afforded Cp?Ru(mu-H)3IrCp?(6a) by sequential salt metathesis and beta-hydrogen elimination. CpsRu(mu-H)3ML [Cps = Cp?, Cp?; ML = IrCp?, RhCp?, Ru(p-cymene), Ru(benzene)] were also selectively synthesized by reacting a mixture of CpsRuCl/n and [LM(mu-Cl)Cl]2 via the formation of CpsRu(mu-Cl)3ML. The IrCp?, RhCp?, and Ru(arene) complexes, Cp?Ru(mu-H)3IrCp?(6b), Cp?Ru(mu-H)3RhCp?(8), and Cp?Ru(mu-H)3Ru(arene) (10), were newly synthesized by this method. The reaction mechanism was discussed based on the hetero-bimetallic chloro-hydride intermediates. Absence of main group hydride reagents was responsible for maintaining the hetero-bimetallic structure during the introduction of the hydride ligand, which lead to selective formation of dinuclear mixed-metal trihydride-bridged complexes.

The dinuclear RuII arene complexes [{(eta6-arene) RuCl}2(mu-2,3-dpp)](PF6)2, arene = indan (1), benzene (2), p-cymene (3), or hexamethylbenzene (4) and 2,3-dpp = 2,3-bis(2-pyridyl)pyrazine, have been synthesized and characterized. Upon irradiation with UVA light, complexes 1 and 2 readily underwent arene loss, while complexes 3 and 4 did not. The photochemistry of 1 was studied in detail. In the X-ray structure of [{(eta6-indan)RuCl}2(mu-2,3- dpp)](PF6)2 (1), 2,3-dpp bridges two RuII centers 6.8529(6) A apart. In water, aquation of 1 in the dark occurs with replacement of chloride with biexponential kinetics and decay constants of 100 ± 1 min-1 and 580 ± 11 min-1. This aquation was suppressed by 0.1 M NaCl. UV or visible irradiation of 1 in aqueous or methanolic solution led to arene loss. The fluorescence of the unbound arene is ?40 times greater than when it is complexed. Irradiation of 1 also had a significant effect on its interactions with DNA. The DNA binding of 1 is increased after irradiation. The non-irradiated form of 1 preferentially formed DNA adducts that only weakly blocked RNA polymerase, while irradiation of 1 transformed the adducts into stronger blocks for RNA polymerase. The efficiency of irradiated 1 to form DNA interstrand cross-links was slightly greater than that of cisplatin in both 10 mM NaClO4 and 0.1 M NaCl. In contrast, the interstrand cross-linking efficiency of non-irradiated 1 in 10 mM NaClO 4 was relatively low. An intermediate amount of cross-linking was observed when the sample of DNA already modified by non-irradiated 1 was irradiated. DNA unwinding measurements supported the conclusion that both mono- and bifunctional adducts with DNA can form. These results show that photoactivation of dinuclear RuII arene complexes can simultaneously produce a highly reactive ruthenium species that can bind to DNA and a fluorescent marker (the free arene). Importantly, the mechanism of photoreactivity is also independent of oxygen. These complexes, therefore, have the potential to combine both photoinduced cell death and fluorescence imaging of the location and efficiency of the photoactivation process.

Eight amino alcohol-modified beta-CDs CD-1-CD-8 have been synthesized in acceptable yields and were employed to form artificial metalloenzymes with [RuCl2(Benzene)]2 and [RuCl2(Mesitylene)] 2, respectively. All the conformations of CD-1-CD-8, the complexes between CD-1-CD-8 and [RuCl2(Arene)]2, and the inclusion complexes between CD-1-CD-8 and acetophenone were characterized by UV, 1H NMR, 1H ROESY NMR, and quantum calculation. The catalytic activity of the formed artificial metalloenzymes in the asymmetric hydrogenation of aromatic ketones, especially the effect of the aromatic ligands’ volume on the enantioselectivity were investigated in detail, in which it was obvious that the enantioselectivity increased as the increase in the aromatic ligands’ volume. For the best artificial metalloenzyme constructed from the complex between CD-8 and [RuCl2(Mesitylene)]2, which not only exhibits a good tolerance to a wide range of substrates but also demonstrates some substrate selectivity, 76.39% ee was obtained for acetophenone and 79.67% ee for 2-acetylnaphthalene. A strategy to improve the enantioselectivity in the asymmetric reactions catalyzed by the artificial metalloenzymes based on CDs has been provided.

(eta6-C6H6)(eta6-[3 n]Cyclophane)Ru(II) [BF4]2 and corresponding Os(II) [PF6]2, as well as bis(eta5-C5H5)(eta6,eta 6-[3n]cyclophane)Fe(II)Fe(II) [PF6]2 ([3n]cyclophane = [32](1,4)cyclophane 2, [33](1,3,5)cyclophane 3, [34](1,2,3,5)cyclophane 4, [34](1,2,4,5)cyclophane 5) have been synthesized and characterized. The complexation shifts of the 1H-NMR signals of the metal-bound aromatic protons (Hb) are ca. 0.5-0.7 and 0.1-0.4 ppm for Fe(II) and Ru(II) complexes, respectively, whereas those of Os(II) complexes are ca. -0.2-0.1 ppm. The complexation shifts of the 13C-NMR signals of the tertiary aromatic carbons of the metal-bound benzene ring are ca. 39-42 and 45-50 ppm for Ru(II) and Os(II) complexes, respectively. Thus the 1H- and 13C-NMR chemical shifts of the metal-bound aromatic hydrogens and carbons are strongly influenced by the anisotropy effect of the metal. The Ru(II) complexes showed electrochemically reversible responses. In the case of Os(II) complexes, a well-defined cathodic peak was also observed, but the rising portion of the corresponding anodic peak was somewhat deviated from the ordinary CV profile. In both cases, the redox process was attributed to the two-electron one-step mechanism, M(II) ? M(0) (M = Ru and Os). An analysis of the redox properties of the Ru(II) and Os(II) complexes suggested that the Os(II)[34](1,2,4,5)cyclophane complex would be the most suitable subunit of an anticipated one-dimensional organometallic polymer.
