-Au(PPh3), (x = 3, 4, 6) with Ru3(CO)10(NCMe)2. The bis-cluster complex 1,4-{AuRu3(CO)9(PPh3)(μ3-C2)}2C6H4 was obtained from Ru3(CO)10(NCMe)2 and 1,4-{(Ph3P)Au(C≡C)}2C6H4. The complexes Ru3(μ-H){μ3-C2C≡C[Ru(PP)Cp′]}(CO)9 [PP = (PPh3)2, Cp′ = Cp; PP = dppe, Cp′ = Cp*] were also obtained as minor by-products and synthesised independently from Ru(C≡CC≡CH)(PP)Cp′.
A reaction between Co3{μ3-CC≡CC≡CAu(PPh3)}(μ-dppm)(CO)7 and Ru3(CO)12 afforded {(Ph3P)(OC)9AuRu3}C≡CC≡CC{Co3(μ-dppm)(CO)7} 7. Related complexes AuRu3{μ3-C2C≡[M(CO)2Tp]}(CO)9(PPh3) (M = Mo 8, W 9) were obtained from {Tp(OC)2M}≡CC≡C{Au(PPh3)}, while the mixed metal cluster complexes MoM2(C2Me)(CO)8Tp (M = Ru 13, Fe 14) were obtained from M(≡CC≡CSiMe3)(CO)2Tp (M = Mo, W) with Fe2(CO)9 and Ru3(CO)12, respectively. Reactions of the Mo carbyne complex with Co2(LL)(CO)6 [LL = (CO)2, μ-dppm] or nickelocene afforded complexes 15–17 in which Co2 and Ni2 fragments, respectively, had coordinated to the C≡C triple bond. XRD structural determinations of 7, 8, 14, 16 and {Tp(OC)2W}≡CC≡CC≡{Co3(μ-dppm)(CO)7} (18-W) are reported.

The crystal structures of two copper(II) complexes of the cyclohexanecarboxylate ligand, namely [Cu(C6H11CO2)2(H2O)2]·H2O (1) and [Cu(dpyam)2(C6H11CO2)](NO3)·H2O (2) (C6H11CO2H = cyclohexanecarboxylic acid; dpyam = di-2-pyridylamine), have been determined by single-crystal X-ray analysis. Complex
1 contains the square-planar trans-CuO4 chromophore, while 2 shows the square pyramidal cis-distorted octahedral CuN4OO′ chromophore. Both complexes were found to show strong inhibitory activity against jack bean urease (IC50 = 1.75 and 8.57 μM for 1 and 2, respectively), when compared with acetohydroxamic acid (IC50 = 63.12 μM). 相似文献

Abstract Three new complexes, [Co(L)2(SCN)2] (1), [Co2(L)4(μ-N3)2](ClO4)2(H2O)1.5 (2), and [Ni(L)3](ClO4)2(CH3OH)2 (3), have been synthesized and structurally characterized, where L is 3-(3′,5′-dimethyl-pyrazole)-6-Cl-pyridazine. Single crystal
X-ray analyses show that all three complexes crystallize in the monoclinic crystal system. In complex (1), the Co(II) atom is in a distorted octahedral environment consisting of four nitrogen atoms from two ligands and two nitrogen
atoms of SCN−, which is further extended into a 1D chain by intermolecular hydrogen bonds. Two Co(II) atoms in complex (2) are linked by two azide anions in a μ-1,1 mode to make a binuclear structure. Without any auxiliary ligand, the Ni(II) atom
in complex (3) adopts a distorted octahedral geometry involving six nitrogen atoms from three ligands. The electronic absorption spectra
of the title compounds are discussed as well. The effects of auxiliary ligands on the structures and properties of the title
complexes have been studied and discussed.
Graphical Abstract Three new complexes, [Co(L)2(SCN)2] (1), [Co2(L)4(μ-N3)2](ClO4)(H2O)1.5 (2) and [Ni(L)3](ClO4)2(CH3OH)2 (3), have been synthesized and structurally characterized, where L is 3-(3′,5′-dimethyl-pyrazole)-6-Cl-pyridazine. Complexes
(1) and (3) are mononuclear compounds, which are different from the binuclear complex (2). Auxiliary ligands are the main reasons that results in the different structures of the title complexes and their different
fungicidal activities.

Abstract
Two new neutral mononuclear Zn(II) and Mn(II) complexes with pyridine-2-amidoxine and carboxylate ligands, [Zn(paH)2(OAc)2]·2CH3OH (paH = pyridine-2-amidoxine, HOAc = acetic acid) (1), and [Mn(paH)2(OAc)2]·C2H5OH·2H2O (2), have been prepared and characterized structurally by X-ray crystallography. 1 and free paH exhibit photoluminescence at room temperature in solid state, which is rare so fare for metal complexes with oxime-based ligand. The emissions of 1 and free paH arise from the metal-perturbed paH-based π → π* ligand-to-ligand charge transfer transition (LLCT) and π → π* charge transfer transition in nature, respectively, in terms of the density functional theory level calculations and molecular orbital analyses. 相似文献6.

New trans-platinum complexes of clotrimazole (CTZ) have been prepared and characterized. Their interaction with DNA and activity against
tumour cell lines were evaluated. [Pt (CTZ)2I2] (1) was synthesized by the reaction of K2PtCl4, KI and CTZ, and [Pt(CTZ)2Cl2] (2) by direct reaction of K2PtCl4 with CTZ. These complexes were characterized by a combination of elemental analysis, molar conductivity, UV–Vis, IR, and
NMR spectroscopy in one and two dimensions. DNA–platinum complex interactions were studied by spectroscopic, thermal denaturation
and viscosity titration measurements. Covalent interaction studies were also performed. From these results we suggest that
complexes 1 and 2 interact with the minor groove of DNA. Both complexes showed growth inhibitory effects on four out of the six tumour cells
lines with GI50 (50% growth inhibition) values in the 5–25 μM range, but there was no indication of cytotoxicity over the range of concentrations
tested. 相似文献

Abstract
Three nickel(II) complexes, namely [Ni(BH)3](H2O)(NO3)(ClO4) 1, [Ni(BH)2(NO3)2] 2 and [Ni(BH)(Tren)](ClO4)2 3 (BH = Benzoylhydrazine, Tren = Tris(2-aminoethyl)amine) have been synthesized and characterized by physico-chemical techniques. X-ray crystallographic analysis shows the nickel to be six-coordinated in these complexes. The complexes are efficient catalysts for the dismutation of superoxide in alkaline DMSO-NBT assays. The IC50 values are 74,108 and 105 μM for 1, 2 and 3, respectively. 相似文献8.

The reactions of Cp(CO)2Re=C=CHPh (2) with M(PPh3)4 (M = Pd, Pt) gave the μ-vinylidene complexes Cp(CO)2RePd(μ-C=CHPh)(PPh3)2 (3) and Cp(CO)2RePt(μ-C=CHPh)(PPh3)2 (1), respectively. The substitution of Ph2PCH2PPh2 (dppm) for the PPh3 ligands in 1 resulted in the formation of Cp(CO)RePt(μ-C(1)=C(2)HPh)(μ-CO)(dppm) (4). The structure of complex 4 has been determined by single-crystal X-ray diffraction analysis. The structural and spectroscopic characteristics of complexes
1, 3, and 4 were compared with the corresponding parameters of the manganese-containing analogs Cp(CO)2MnPd(μ-C=CHPh)(PPh3)2 (5), Cp(CO)2MnPt(μ-C=CHPh)(PPh3)2 (6) and Cp(CO)2MnPt(μ-C=CHPh)(dppm) (7). 相似文献

Two CoII complexes, namely {[CoL(MeOH)(μ-OAc)]2Co}·2MeCN·2MeOH (1) and {[CoL(EtOH)(μ-OAc)]2Co}·3EtOH (2) (H2L=3,3′-dimethoxy-2,2′-[(1,3-propylene)dioxybis(nitrilomethylidyne)]diphenol), have been synthesized and characterized by X-ray
crystallography. Both complexes contain octahedral coordination geometries, comprising three CoII atoms, two deprotonated bisoxime L2− units in which four μ-phenoxo oxygen atoms form two [CoL(X)] (X = MeOH or EtOH) units, two acetate ligands coordinated to
three CoII centers through Co–O–C–O–Co bridges, and coordinated and non-coordinated solvent. Both complexes exhibit 2D supramolecular

Tris(N-methylbenzimidazol-2-ylmethyl)amine (Mentb) and its two complexes, [Mn(Mentb)(DMF)(H2O)](pic)2
1 and [Zn(Mentb)(pic)](pic) 2 (pic = picrate), have been synthesized and characterized by physico-chemical and spectroscopic methods. Single crystal X-ray
diffraction revealed that the two complexes have different structures. In complex 1, the coordination sphere around Mn(II) is distorted octahedral, whereas in complex 2 the coordination sphere around Zn(II) is distorted trigonal bipyramidal. The DNA-binding properties of the free ligand and
its two complexes have been investigated by electronic absorption, fluorescence, and viscosity measurements. The results suggest
that the ligand and its two complexes bind to DNA via an intercalation binding mode, and their binding affinity for DNA follows
the order 1 > 2 > ligand. 相似文献

The difurylphosphido-bridged dinuclear complex [Ru2(CO)6(μ-PFu2)(μ-η1,η2-Fu)] (Fu = 2-furyl) 1 readily reacts with two equivalents of each of the terminal alkynes HC≡CR (R = Fc, p-C6H4Fc, p-C6H4NO2, Fc = Fe(η5-C5H5)(η5-C5H4)) by an interesting head-to-tail ynyl coupling with a furan group to form a series of phosphido-bridged diruthenium compounds
containing a novel furyl-substituted C4 hydrocarbyl chain of stoichiometry [Ru2(CO)4(μ-PFu2){μ-η1,η1,η2,η3-RCC(H)C(R)C(H)Fu}] (R = Fc 2, p-C6H4Fc 3, p-C6H4NO2
4) in moderate to good yields. Reaction of 1 with an equimolar amount of HC≡CFc and HC≡C(p-C6H4NO2) afforded a pair of isomers of [Ru2(CO)4(μ-PFu2){μ-η1,η1,η2,η3-R1CC(H)C(R2)C(H)Fu}] (R1 = Fc, R2 = p-C6H4NO2
5a; R1 = p-C6H4NO2, R2 = Fc 5b) together with a small mixture of 4. X-ray crystal structures of 2, 3, 5a and 5b are reported. All of these new alkyne-derived dinuclear complexes are electron precise with 34 cluster valence electrons
in which the μ-η1,η2-furyl ligand acts as a three-electron donor and the μ-phosphido Ru2 framework is retained in the products upon alkyne coupling reactions. The resulting organic fragment of each complex is coordinated
to the Ru atoms via a π, a π-allyl and two σ bonds, and donates seven electrons to the metal core.

The reaction of [PtMe3(bpy)(Me2CO)](BF4) (2) (prepared from [PtMe3I(bpy)] (1) plus Ag(BF4)) with MeSSMe resulted in the formation of [PtMe3(bpy)(MeSSMe-κS)](BF4) (3). A single-crystal X-ray diffraction analysis revealed in the octahedral Pt(IV) complex (configuration index: OC-6-33), a conformation of the monodentately κS bound MeSSMe ligand (C–S–S–C 92.7(4)°) being very close to that in non-coordinated MeSSMe, thus allowing some hyperconjugative
interaction stabilizing the S–S bond. The reaction of [K(18C6)][(PtMe3)2(μ-I)(μ-pz)2] (4; 18C6 = 18-crown-6, Hpz = pyrazole) with Ag(BF4) and MeSSMe resulted in the formation of dinuclear complexes [(PtMe3)2(μ-pz)2(μ-MeSSMe)] existing at room temperature in acetone solution as different fast interconverting isomers. At –40 °C, two isomers
with a μ-1κS:2κS (5a) and a μ-1κS:2κS′ (5b) coordinated MeSSMe ligand in the ratio 2:1 could be identified 1H NMR spectroscopically. DFT calculations of type 5 complexes revealed the existence of two conformers with a μ-MeSSMe-1κS:2κS ligand, which differ mainly in the C–S–S–C dihedral angle (66.4 vs. 180.0° 6a/6a′). They have essentially the same energy and a very low activation barrier in acetone as solvent (1.3 kcal/mol) for their
mutual interconversion. A further equilibrium structure was identified to be an isomer having a μ-MeSSMe-1κS:2κS′ ligand (6b) that proved to be only 1.9 kcal/mol higher in energy than 6a/6a′. 相似文献

Abstract
Reaction of the [Me4N]2[Cd(SPh-4-Me)4] with two equivalents of [M(PPh3)2NO3] afforded the neutral linear trinuclear complexes [Cd(μ-SPh-4-Me)4{M(PPh3)2}2] (M = Cu 1, Ag 2) in which two [M(PPh3)2]+ fragments chelate with the opposite edges of a tetrahedral [Cd(SPh-4-Me)4]2− moiety via the sulfur atoms of the Me-4-PhS− species. Treatment of [Sn(SPh)4] with two equivalents of [Ag(PPh3)2NO3] gave the neutral linear trinuclear complex [Sn(μ-SPh)6(AgPPh3)2] (3) that is composed of a central distorted SnS6 octahedron sharing two opposite planes with two slightly distorted AgS3P tetrahedrons. Complexes 2 and 3 are air and optically stable. Their nonlinear optical absorption and refraction were investigated under the same conditions. The nonlinear optical absorption and refraction of complex 2 were determined to be α 2 = 3.11 × 10−11 m/W and n 2 = 4.15 × 10−12 esu, respectively. The nonlinear optical absorption and refraction of complex 3 were determined to be α 2 = 8.36 × 10−11 m/W and n 2 = 1.47 × 10−11 esu, respectively. 相似文献15.

Two ruthenium(II) polypyridyl complexes, namely [Ru(phen)2(DMDPPZ)](ClO4)2
1 (phen = 1,10-phenanthroline, DMDPPZ = 3,6-dimethyldipyrido[3,2-a:2′,3′-c]phenazine) and [Ru(dmp)2(DMDPPZ)](ClO4)2
2 (dmp = 2,9-dimethyl-1,10-phenanthroline), have been synthesized and characterized. The DNA-binding properties of the complexes
were investigated by spectrophotometric methods, viscosity measurements, and photoactivated cleavage studies. The DNA-binding
constants for complexes 1 and 2 have been determined as 8.78 (±0.94) × 105 M−1 (s = 3.02) and 1.26 (±0.35) × 105 M−1 (s = 1.69), respectively. The results suggest that these complexes bind to calf thymus DNA through intercalation. When irradiated
at 365 nm, the complexes promote the photocleavage of pBR322 DNA, and complex 1 cleaves DNA more effectively than complex 2 under comparable experimental conditions. The cytotoxicities of complexes 1 and 2 have been evaluated by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide) method. Complex 2 shows higher anticancer potency than complex 1 against four tumor cell lines. The apoptosis-inducing activity was assessed by acridine orange/ethidium bromide staining
assay, and the antioxidant activities of these complexes against hydroxyl radical were also explored. 相似文献

Hydrazine forms two different types of complexes with divalent metal ions and pyromellitic acid (H4pml) in aqueous medium: (i) hydrazinium complexes of formulae, (N2H5)2M(pml)·xH2O, where x = 3 for M=Ni and x = 4 for M=Co or Zn, and (N2H5)2Mn(H2pml)2, at pH 4.5, (ii) neutral hydrazine complexes with formulae, M2(pml)(N2H4)
n
·xH2O where M=Co or Ni when n = 4 and x = 5 or 4 and M=Zn or Cd when n = 2, and x = 4 or 3 at pH 7, and M(H2pml)(N2H4)·xH2O where x = 4; M=Cu and x = 0; M=Hg, at pH 3, 7.5, respectively. All the complexes are insoluble in water, alcohol and ether. The N–N stretching frequency
(990–1,007 cm−1 for coordinated hydrazinium ion and 956–985 cm−1 for bridged neutral hydrazine) indicates the nature of hydrazine present in the complexes. Simultaneously TG-DTA analysis
indicates that hydrazinium complexes undergo dehydration and dehydrazination in a single step endothermally in the range of
289–300 °C whereas neutral hydrazine complexes undergo endothermic dehydration (~100 °C) followed by exothermic dehydrazination
in the temperature range, 253–332 °C. The anhydrous metal carboxylates further decompose exothermally to leave the respective
metal oxides or metal carbonates except zinc, which gives its oxalate as the end product. X-ray powder patterns indicate that
even the complexes with the same formulation possess no isomorphism. 相似文献

The mononuclear Cu(II) complex [Cu(phen)(H2O)(NO3)2] (1), obtained by the reaction of 1,10-phenanthroline with Cu(NO3)2·3H2O in methanol solution, reacts with anionic ligands SCN−, AcO−, N3
− and PhCO2

− (4) or PhCO2
−(5). The molecular structure of complex 3 was determined by single-crystal X-ray diffraction studies. These complexes were characterized by electronic, IR, ESR, magnetic
moments and conductivity measurements. The electrochemical behaviour of the complexes was investigated by cyclic voltammetry.
The interactions of these complexes with calf thymus DNA have been investigated using absorption spectrophotometry. Their
DNA cleavage activity was studied on double-stranded pBR322 plasmid DNA using gel electrophoresis experiments in the absence
and presence of H2O2 as oxidant. 相似文献

The gold complexes Au(C≡CC6H4C≡CC6H4Me)(PPh3) (3) and {Au(PPh3)}2(μ-C≡CC6H4C≡CC6H4C≡CC6H4C≡C) (6), prepared from the reaction of AuCl(PPh3) with the corresponding terminal or trimethylsilyl protected alkynes, react readily with Ru3(CO)10(μ-dppm) to afford phenylene ethynylene derivatives featuring the Ru3(μ-AuPPh3)(μ-C2R)(CO)7 cluster “end-caps”. The hydrido cluster Ru3(μ-H)(μ-C2C6H4C≡CC6H4Me)(CO)7 (4a) has also been obtained. There are significant differences in the absorption spectra of the organic precursors, the gold complexes and the clusters indicate a mixing of electronic states between the cluster and phenylene ethynylene moieties, while the presence of the Ru3 and in particular Ru3(μ-AuPPh3) cluster end-caps leads to a quenching of the phenylene ethynylene centred emission. The crystallographically determined structures of 3, 4a and Ru3(μ-AuPPh3) (μ-C2C6H4C≡CC6H4Me)(CO)7 (4b) are reported.Dedicated to Professor B.F.G.

A new coordination polymer with interesting supramolecular architecture, [Zn(4-tzbz)]
n
(1) (4-tzbz = 4-(tetrazol-5-yl)benzoate), has been synthesized and characterized structurally. In this compound, the zinc(II)
ions are connected by the tetrazole ring in the μ2-1,4 bridging mode and the carboxylate group in the μ2-1,3 syn-anti bridging mode to generate 2D (4,4) sheets, and the adjacent sheets are linked further by the benzene rings to give the 3D
metal–organic framework with a 3,4-connected (83)(84122) topology. This compound in the solid state exhibits photoluminescence assignable to intraligand transitions, and, in particular,
the emission at 400 nm is significantly intensified due to the coordination of the ligand to Zn. 相似文献
