The organometallic osmium(VI) hydroxo compounds [N(n-Bu) 4][Os(N)(CH2SiMe3)3(OH)], cis and trans isomers of [N(n-Bu)4][Os(N)(CH2SiMe 3)2(OH)2], result from the substitution of chloride for hydroxide ligands in precursor compounds. Depending on the molecular structure, these compounds behave as nucleophiles, Bronsted bases, or Lewis bases in their reactions. One of these, [N(n-Bu) 4][cis-Os(N)-(CH2SiMe3)2(OH) 2], reacts readily with CO2 to produce the carbonate compound [N(n-Bu)4][Os(N)(CH2-SiMe3) 2(CO3)]. The other isomer, [N(n-Bu)4][trans- Os(N)(CH2SiMe3)2(OH)2], reacts with CO2 to slowly form the same carbonate compound. It is protonated by other acids to give the neutral hydroxo dimer {Os(N)(CH2SiMe 3)2(mu-OH)}2. The and isomer of {Os(N)(CH2SiMe3)2(mu-OH)}2 reacts with Pd(bpy)-(OSiMe3)2 to produce the coordinatively unsaturated, heterometallic complex {Os(N)(CH2SiMe3) 2}2(mu3-O)2Pd(bpy). The molecular structure of this complex shows two square-pyramidal osmium groups with an anti arrangement of the apical nitrido ligand and a square-planar palladium(II) center, all connected by the triply bridging oxo groups.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of (2,2′-Bipyridine)dichloropalladium(II), you can also check out more blogs about14871-92-2

An N-butyl derivative of 2,6-bis(1-butyl-1H-benzo[d]imidazol-2-yl)pyridine was used to prepare a series of five manganese(II) complexes, which were characterised by spectroscopic and analytical methods. The molecular structures of the complexes were determined by single crystal X-ray crystallography. The complexes contain five, six or seven-coordinate manganese(II) ions, depending on the counter ions. The complexes [Mn(L)Cl2] and [Mn(L)(NCS) 2] have five-coordinate manganese centres, while [Mn(L) 2](ClO4)2 is six-coordinate. In [Mn(L)(NO 3)2], both nitrate ions behave as bidentate chelating ligands, resulting in a seven-coordinate complex. The N-butyl benzimidazole ligand is tridentate in all the complexes. All of the complexes are active catalase mimics and [Mn(L)Cl2] is the most efficient catalyst for the disproportion hydrogen peroxide, with a turnover number of 68 s-1.

Abstract The rational design of metal-based complexes is an effective strategy for the discovery of potent sensitizers for use in cancer radiotherapy. In this study, we synthesized three ruthenium complexes containing bis-benzimidazole derivatives: Ru(bbp)Cl3 (1), [Ru(bbp)2]Cl2 (2 a) (in which bbp=2,6-bis(benzimidazol-1-yl)pyridine), and [Ru(bnbp)2]Cl2 (2 b) (where bnbp=2,6-bis-(6-nitrobenzimidazol-2-yl)pyridine). We evaluated their radiosensitization capacities in vitro and mechanisms of action. Complex 2 b was found to be particularly effective in sensitizing human melanoma A375 cells toward radiation, with a sensitivity enhancement ratio of 2.4. Along with this potency, complex 2 b exhibited a high degree of selectivity between human cancer and normal cells. Mechanistic studies revealed that 2 b promotes radiation-induced accumulation of intracellular reactive oxygen species (ROS) by reacting with cellular glutathione (GSH) and then causing DNA stand breaks. The subsequent DNA damage induces phosphorylation of p53 (p-p53) and upregulates the expression levels of p21, which inhibits the expression of cyclin-B, leading to G2M arrest. Moreover, p-p53 activates caspases-3 and -8, triggers cleavage of poly(ADP-ribose) polymerase (PARP), finally resulting in apoptosis. Taken together, the results of this study provide a strategy for the design of ruthenium-based radiosensitizers for use in cancer therapy.

Abstract New palladium(II) complexes with tryptamine (Pd-tra) and mefenamic acid (Pd-mef) were prepared and characterized by chemical and spectroscopic methods. Elemental, ESI-QTOF mass spectrometric and thermogravimetric analyses of the compounds confirm the composition [PdCl2(tra)2] for Pd-tra and [Pd(mef)2(bipy)] for Pd-mef. Infrared data indicate the coordination of tryptamine to Pd(II) by the nitrogen atom of the amino group, while for mefenamic acid coordination occurs by the oxygen atom of carboxylate group in a monodentate form. The 1H, 13C and {15N,1H} NMR spectroscopic data confirm the nitrogen coordination of the NH2 group of trypatmine to Pd(II) in the Pd-tra complex and also the oxygen coordination of the carboxylate group of mefenamic acid to Pd(II) in the Pd-mef complex. Density functional theory (DFT) studies were applied to determine the difference in energy between the geometric isomers (cis/trans) of Pd-tra and to optimize the structure of the Pd-mef complex. Raman spectroscopic measurements reinforce the nitrogen coordination of tryptamine to Pd(II) in the Pd-tra complex and confirms the presence of the cis-[PdCl2(tra)2] isomer in the solid state. The complexes are insoluble in water.

The nickel and platinum complexes [MX2(dppe)] (X = Cl, Br) react with bi- and tri-valent metal diethyldithiocarbamates [M?(S2CNEt2)n] (M? = Pb, Zn, Cd, Hg, Ni, MoO2, VO, n = 2; M? = Co, Fe, Mn, n = 3) to afford salts [M(S2CNEt2)(dppe)]2[M?X4]; reactions involving [Cu(S2CNEt2)2] and [Ag(S2CNEt2)] gave salts of the form [M(S2CNEt2)(dppe)][M?X2] (M? = Cu, Ag). The complexes cis [RuCl2(dppm)2], [CoCl2(dppe)] and [PdX2(bipy)] likewise react with the same dithiocarbamates to form salts [Ru(S2CNEt2)(dppe)2]2 [M?Cl4] [Co(S2CNEt2)2(dppe)]2 [M?Cl4] and [Pd(S2CNnBu2)(bipy)]2 [M?X4], respectively. Sample reactions involving other S-chelate ligands – S2COEt-, S2PPh2- and S2P(OEt)2- – appear to follow the same general pattern. However, the O-ethyldithio carbonates (ethylxanthates) are partly converted to the corresponding dithiocarbonates. An anomalous reaction between [CoCl2(dppe)] and [Zn(S2CNEt2)2] in the presence of (S2CNEt2)2 affords the novel complex [Co(S2CNEt2)2(dppe)]2[Cl 3ZnO:(Ph)2PCH2CH2P(Ph) 2:OZnCl3]. A selection of these salts have been fully characterised by elemental analysis and spectroscopic techniques, the remainder have been identified by spectroscopic methods alone. X-ray crystal structures are reported for the salts [Ni(S2CNEt2)(dppe)]2 [HgBr4], [Pt(S2CNEt2)(dppe)]2[CdCl4], [Co(S2CNEt2)2(dppe)]2[Cl 3ZnO:(Ph)2PCH2CH2P(Ph) 2:OZnCl3] and [Pd(S2CNnBu2) (bipy)]2[CdCl4].
