Two silver(I) complexes were prepared by the reaction of [Ag(C(CPh)]n with NP3 [NP3 = N(CH2CH2PPh2)3] or with NP3 and [Cu(CH3CN)4]ClO4. Complex 1 [(Ag2Cl(NP3)2)(Ag5(C(CPh)6)] contains both NP3 and PhC(C- ligands. The complex cation is (Ag2Cl(NP3)2)+, in which two Ag(NP3)+ cations were bridged by a Cl- donor. The anion is (Ag5(C(CPh)6)-, where five Ag+ ions are linked by six C(CPh- to form a pentanuclear cluster. Complex 2 only contains NP3 ligand, where the silver center adopts a trigonal-bipyramidal geometry.

Ruthenium(II) complexes with chelating polypyridine ligands are among the most frequently investigated compounds in photophysics and photochemistry, owing to their favorable luminescence and photoredox properties. Equally good photoluminescence performance and attractive photocatalytic behavior is now achievable with isoelectronic molybdenum(0) complexes. The zero-valent oxidation state of molybdenum is stabilized by carbonyl or isocyanide ligands, and metal-to-ligand charge transfer (MLCT) excited states analogous to those in ruthenium(II) complexes can be established. Microsecond MLCT excited-state lifetimes and photoluminescence quantum yields up to 0.2 have been achieved in solution at room temperature, and the emission wavelength has become tunable over a large range. The molybdenum(0) complexes are stronger photoreductants than ruthenium(II) polypyridines and can therefore perform more challenging chemical reductions. The triplet nature of their luminescent MLCT states allows sensitization of photon upconversion via triplet-triplet annihilation, to convert low-energy input radiation into higher-energy output fluorescence. This review summarizes the current state of the art concerning luminescent molybdenum(0) complexes and highlights their application potential. Molybdenum is roughly 140 times more abundant and far cheaper than ruthenium, hence this research is relevant in the greater context of finding more sustainable alternatives to using precious and rare transition metals in photophysics and photochemistry. 相似文献

Three luminescent mononuclear RuII compounds, [RuII(bpy)2( L1 )](BF4) ( 1 ), [RuII(bpy)2( L2 )](BF4) ( 2 ), and the neutral compound [RuII(bpy)2( L3 )] ( 3 ), were obtained, by treatment of [RuII(bpy)2Cl2] with the tetrazolate (tz)-containing ligands L1 – L3 . All the compounds were well characterized by IR, UV/Vis, and 1H NMR and their redox properties were also investigated by cyclic voltammogram. The crystal structure of 3 was determined by X-ray crystallography and it clearly shows that the RuII ion is octahedrally coordinated by two bpy ligands and a deprotonated L3 ligand. After introduction of these tz ligands, 1 – 3 are more sensitive towards the change of micro-environment of solvents as compared with that of [RuII(bpy)3]2+. This effect is most obvious in 3 , since it contains a 2– ligand L3 . The slight modification of diimine ligand make these complexes have potential applications as sensors. 相似文献

Several new hexa-coordinated ruthenium(II) and penta-coordinated rhodium(I) complexes of the types [RuCl(CO)(PPh 3 ) 2 (TSC)], [RuH(CO)(PPh 3 ) 2 (TSC)], and [Rh(PPh 3 ) 3 (TSC)] (where TSC = anion of thiosemicarbazone Schiff bases) have been prepared by the reactions of [RuHCl(CO)(PPh 3 ) 3 ], [RuH 2 (CO)(PPh 3 ) 3 )], and [RhH(PPh 3 ) 4 ] with thiosemicarbazones of 2-furaldehyde (H-FTSC), thiophene-2-carboxaldehyde (H-TCTSC), p-anisaldehyde (H-ATSC), piperonaldehyde (H-PTSC), and cyclohexanone (H-CTSC). All the new complexes obtained have been characterized on the basis of elemental analysis, IR, 1 H NMR, 31 P NMR, and electronic spectral data. 相似文献

Reaction of [1,2‐(Cp*RuH)2B3H7] ( 1 ; Cp*=η5‐C5Me5) with [Mo(CO)3(CH3CN)3] yielded arachno‐[(Cp*RuCO)2B2H6] ( 2 ), which exhibits a butterfly structure, reminiscent of 7 sep B4H10. Compound 2 was found to be a very good precursor for the generation of bridged borylene species. Mild pyrolysis of 2 with [Fe2(CO)9] yielded a triply bridged heterotrinuclear borylene complex [(μ3‐BH)(Cp*RuCO)2(μ‐CO){Fe(CO)3}] ( 3 ) and bis‐borylene complexes [{(μ3‐BH)(Cp*Ru)(μ‐CO)}2Fe2(CO)5] ( 4 ) and [{(μ3‐BH)(Cp*Ru)Fe(CO)3}2(μ‐CO)] ( 5 ). In a similar fashion, pyrolysis of 2 with [Mn2(CO)10] permits the isolation of μ3‐borylene complex [(μ3‐BH)(Cp*RuCO)2(μ‐H)(μ‐CO){Mn(CO)3}] ( 6 ). Both compounds 3 and 6 have a trigonal‐pyramidal geometry with the μ3‐BH ligand occupying the apical vertex, whereas 4 and 5 can be viewed as bicapped tetrahedra, with two μ3‐borylene ligands occupying the capping position. The synthesis of tantalum borylene complex [(μ3‐BH)(Cp*TaCO)2(μ‐CO){Fe(CO)3}] ( 7 ) was achieved by the reaction of [(Cp*Ta)2B4H8(μ‐BH4)] at ambient temperature with [Fe2(CO)9]. Compounds 2 – 7 have been isolated in modest yield as yellow to red crystalline solids. All the new compounds have been characterized in solution by mass spectrometry; IR spectroscopy; and 1H, 11B, and 13C NMR spectroscopy and the structural types were unequivocally established by crystallographic analysis of 2 – 6 . 相似文献

Summary. The reaction of RuTp(COD)Cl (1) with PPh2Pri and terminal alkynes HCCR (R=C6H5, C4H3S, C6H4OMe, Fc, C6H4–Fc, C6H9) affords the neutral vinylidene complexes RuTp(PPh2Pri) (Cl)(=C=CHR) (2a–2f) in high yields. These complexes do not react with MeOH to give methoxy carbene complexes of the type RuTp(PPh2Pri)(Cl)(=C(OMe)CH2R), but react with oxygen to yield the CO complex RuTp(PPh2R)(Cl)(CO) (3). The structures of 2b, 2f, and 3 have been determined by X-ray crystallography. 相似文献

Salen-type Ru(III) complexes are found to be capable of reacting with physiologically acceptable oxidants. The water solubility and DNA affinity of these Ru(III)-salen complexes are enhanced by the utilization of a variety of charged groups through the formation of peptide bonds. In the presence of hydrogen peroxide, modified Ru(III)-salen complexes are capable of nicking DNA. In addition, the reactivity in DNA cleavage increases along with the total number of positive charges retaining in Ru(III)-salen complexes and less influence in the electronic effect. Using 32P-end-labeled oligonucleotides and high resolution polyacrylamide gel electrophoresis, Ru(III)-salen complexes are found to randomly cleave DNA regardless of the DNA secondary conformation such as bulge, inter-loop, or double-stranded regions. The possible reactive species of Ru(III)-salen complexes in DNA cleavage is considered as the hydroxyl radical and high valent oxoruthenium(IV) species according to the UV titration, quenching studies, and reaction with varied oxidants. 相似文献

Summary. The complexes RuTp(cod)X (X = Br− (2), I− (3), CN− (4)) have been obtained by the reaction of RuTp(cod)Cl (1) with KX in boiling MeOH in high yields. The cationic complexes [RuTp(cod)(py)]+ (5), [RuTp(cod)(dmso)]+ (6), and [RuTp(cod)(CH3CN)]+ (7) were prepared as the CF3SO3
− salts by reacting 1 with 1 equivalent of AgCF3SO3 in the presence of the respective co-ligand in CH2Cl2. The crystal structures of 1, 3, 4, 5, 6, and 7 are reported. Structural features are discussed in conjunction with 1H, 13C, and 15N NMR spectroscopic data revealing a linear correlation of 15N chemical shifts and Ru-N (trans to X(L)) bond distances.

The four TeII complexes, cis‐[TeCl2{(iPrNH)2CS}2] ( 1 ), cis‐[TeCl2{(iBuNH)2CS}2] ( 2 ), trans‐[TeCl2{(PhNMe)2CS}2] ( 3 ), and trans‐[TeCl2{(Et2N)2CS}2] ( 4 ), have been synthesised and their molecular structures solved by means of X‐ray crystallography. All four complexes are square planar, those with disubstituted thiourea ligands have a cis configuration, those with tetrasubstituted thioureas have a trans configuration. The Te–S bond lengths in 1 and 2 average 2.4994 and 2.5213 Å, respectively. The Te–Cl bonds trans to the Te–S bonds have average lengths of 2.8754 and 2.8334 Å, reflecting the trans influence of the two disubstituted thioureas. In 3 and 4 with identical ligands trans to each other, the average Te–S and Te–Cl bond lengths are 2.6834 and 2.5964 Å, respectively. 相似文献

Lung cancer is one of the most common malignancies with the highest mortality rate and the second-highest incidence rate after breast cancer, posing a serious threat to human health. The accidental discovery of the antitumor properties of cisplatin in the early 1960s aroused a growing interest in metal-based compounds for cancer treatment. However, the clinical application of cisplatin is limited by serious side effects and drug resistance. Therefore, other transition metal complexes have been developed for the treatment of different malignant cancers. Among them, Ru(II/III)-based complexes have emerged as promising anticancer drug candidates due to their potential anticancer properties and selective cytotoxic activity. In this review, we summarized the latest developments of Ru(II/III) complexes against lung cancer, focusing mainly on the mechanisms of their biological activities, including induction of apoptosis, necroptosis, autophagy, cell cycle arrest, inhibition of cell proliferation, and invasion and metastasis of lung cancer cells. 相似文献

Herein are described some continuing investigations into the reactions of cyano‐alkenes with diynyl‐ruthenium complexes which have resulted in the preparation and characterisation of diynyl‐ruthenium compounds Ru(C≡CC≡CR)(PP)Cp [R = Ph, PP = dppe; R = Fc, PP = dppf; R = CPh=CBr2, PP = (PPh3)2], together with the polycyanobutadienyls Ru{C≡CC[=C(CN)2]CR=CR′(CN)}(PP)Cp′ [R = Fc, (PP)Cp′ = (dppf)Cp; R = H, SiMe3, (PP)Cp′ = (dppe)Cp*] formed by [2 + 2]‐cycloaddition of the cyano‐alkenes to the outer C≡C triple bonds and subsequent ring‐opening reactions. Single‐crystal XRD molecular structure determinations of six complexes are reported. 相似文献
