The new alkoxysilyl-functionalized alkynes [HC≡CCH2N(H)C(=O)N(H)(CH2)3Si(OEt)3] and [HC≡C(C6H4)–N(H)C(=O)N(H)(CH2)3Si(OEt)3] have been synthesized using literature methods. These have been reacted with Fe3(CO)12, Ru3(CO)12 and Co2(CO)8. With the iron carbonyl only decomposition was observed: with Ru3(CO)12 splitting of the alkynes into their parent components and formation of the complexes (μ-H)Ru3(CO)9[HC=N(CH2)3Si(OEt)3], (μ-H)Ru3(CO)9[C–C(C6H4)NH2] and (μ-H)2Ru3(CO)9[HC–CCH3] occurred. Finally, with Co2(CO)8 formation of complexes Co2(CO)6(HC2R) R=(C6H4)NH2, CH2NH(CO)NH(CH2)3Si(OEt)3, (C6H4)NH(CO)NH(CH2)3Si(OEt)3 containing the intact alkynes could be obtained. 相似文献

A spectrophotometric method was used for the molecular complexation of ICl3 with para-substituted meso-tetraarylporphyrins (H2t(4-X)pp; X: OCH3, CH(CH3)2, CH3, H and Cl) in methanol/chloroform (2.5% v/v) solution. The equilibrium constants and the thermodynamic parameters were measured
spectrophotometrically at various temperatures for 1:1 molecular complex formation of meso-tetraarylporphyrins as electron
donors with ICl3 as the electron acceptor. The formation constants for the molecular complexes change according to the following trend: [ICl3(H2t(4-OCH3)pp)]>[ICl3(H2t(4-CH(CH3)2)pp)]>[ICl3(H2t(4-CH3)pp)]>[ICl3(H2tpp)]>([ICl3(H2t(4-Cl)pp)]. Further, the thermodynamic parameters, ΔG

The two acetate-functionalized zirconium(IV)-substituted tungstogermanates, Na8K4[Zr4O2(OH)2(CH3COO)2(α-GeW10O37)2] · 33H2O and Na8Cs4[Zr4O2(OH)2(CH3COO)2(α-GeW10O37)2] · 32H2O, were synthesized by the reaction of ZrOCl2 with [A-α-GeW9O34]10− in pH = 4.8 buffer and their structures were determined by single-crystal X-ray analysis. Both of them contain a centrosymmetric
polyanion [Zr4O2(OH)2(CH3COO)2(α-GeW10O37)2]12− consisting of two {α-GeW10O37} units sandwiching an inorganic–organic hybrid {Zr4O2(OH)2(CH3COO)2} cluster. The polyanion contains a mixing of seven- and eight-coordinate Zr centres. The two compounds were also characterized
by elemental analysis, IR spectroscopy, UV–vis and TG–DSC analysis. 相似文献

The etherate of (Ph2SiO)8[Al(O)OH]4 can be transformed into the pyrazine adduct (Ph2SiO)8[Al(O)OH]4 · 3N(C2H2)2N ( 1 ), the ethyl acetate adduct (Ph2SiO)8[Al(O)OH]4 · 3H3C-C(O)OC2H5 ( 2 ), the 1,6-hexane diol adduct (Ph2SiO)8[Al(O)OH]4 · 2HO–CH2(CH2)4CH2–OH ( 3 ) and the 1,4-cyclohexane diol adduct (Ph2SiO)8[Al(O)OH]4 · 4HO–CH(CH2CH2)2CH–OH ( 4 ). In all compounds the OH groups of the starting material bind to the bases through O–H ··· N ( 1 ) or O–H ··· O hydrogen bonds ( 2 , 3 , 4 ) as found from single-crystal X-ray diffraction analyses. Whereas in 1 only three of the central OH groups bind to the pyrazines, in 2 two of them bind to the same carbonyl oxygen atom of the ethyl acetate resulting in an unprecedented O–H ··· O ··· H–O double hydrogen bridge. The hexane diol adduct 3 in the crystal forms a one-dimensional coordination polymer with an intramolecularly to two OH groups grafted hexane diol loop, while the second hexane diol is connecting intermolecularly. In the cyclohexane diol adduct 4 all OH groups of the central Al4(OH)4 ring bind to different diols, leaving one alcohol group per diol uncoordinated. These “free” OH groups form an (O-H ··· )4 assembly creating a three-dimensional overall structure. When reacting with (Ph2SiO)8[Al(O)OH]4 lysine loses water, turns into the cyclic 3-amino-2-azepanone, and transforms through chelation of one of the aluminum atoms the starting material into a new polycycle. The isolated compound has the composition (Ph2SiO)12[Al(O)OH]4[Al2O3]2 · 4 C6H12N2O · 6(CH2)4O ( 5 ). 相似文献

The interaction of Cat2B10H10 (Cat = Ph4P+, Ph4As+) with acetic acid has been studied. Disubstituted closo-decaborate derivatives with a bidentately bound acetate group, Cat[2,6(9)-B10H8>(O)2CCH3], or two monodentate acetate groups, Cat2[2,7(8)-B10H8(OC(O)CH3)2], have been isolated (Cat = Ph4P+, Ph4As+). Hydrolysis of these compounds has led to the position isomers of the [B10H8(OC(O)CH3)(OH)]2? anion with the hydroxo and acetate groups in the 2,6(9)- and 2,7(8)-positions. The structures of {Pb(Bipy)2[2,6(9)-B10H8(OC(O)CH3)(OH)]}2 · 3H2O, (Ph4As)2[2,6(9)-B10H8(OC(O)CH3)(OH)] · 0.4C2H5OH · 0.25H2O, and (Ph4As)2[2,7(8)-B10H8(OC(O)CH3)(OH)], as well as of the product of the reaction of the B10H 10 2? anion with formic acid (Ph4P)2[2-B10H9OC(O)H] · CH3CN, have been determined by X-ray crystallography. 相似文献

[NiL3]X2 (where L=N-phenylethane-1,2-diamine and X=I− and ClO4
−), [NiL2X2] (X is Cl−, Br−, NCS−, 0.5SO4
2− or 0.5SeO4
2−) and [NiL2(H2O)2](NO3)2 have been synthesized from solution and their thermal study has been carried out in the solid phase. [NiL2Cl2] upon heating undergoes irreversible endothermic phase transition (142–152°C, ΔH=0.35 kJ mol−1) without showing any visual colour change. This phase transition is assumed to be due to conformation changes of the diamine
chelate rings. NiLCl2 and NiL2.5I2 have been prepared pyrolytically from [NiL2Cl2] and [NiL3]I2 respectively in the solid state. [NiL2(H2O)2](NO3)2 upon heating undergoes deaquation-anation reaction without showing any visual colour change. [NiL2X2] (X is Cl−, Br−, NCS−), [NiL2(H2O)2](NO3)2 and [NiL2(NO3)2] possess trans-octahedral configuration, whereas, [NiL2X2] (X is 0.5SO4
2− or 0.5SeO4
2−) are having cis-octahedral configuration. Amongst the complexes, only NiLCl2 shows unusually high (5.1 BM at 27°C) magnetic susceptibility value.

Reduced molybdophosphate-based supramolecular compounds, such as (4,4′-H2bipy)[Co(H2O)2]2[Co(H2PO4)2(HPO4)4(PO4)2(MoO2)12(OH)6] · 17H2O (1), [Co(2,2′-bipy)2(H2O)]4[Co(H2O)2][Co(HPO4)6(PO4)2(MoO2)12(OH)6] · 2H2O (2), and [Co(2,2′-bipy)2(H2O)]4[Co(H2PO4)(H2O)2]2[Co(HPO4)6(PO4)2(MoO2)12(OH)6] · 8H2O (3) (4,4′-bipy=4,4′-bipyridine, 2,2′-bipy=2,2′-bipyridine), have been synthesized under hydrothermal conditions and characterized.
Compound 1 exhibits a three-dimensional supramolecular twofold interpenetrating architecture built up of one-dimensional [P4Mo6]-based infinite covalent chains and free 4,4′-bipy molecules. Compound 2 also shows a three-dimensional supramolecular network constructed from one-dimensional covalent [P4Mo6]-based chains. Unlike compounds 1 and 2, compound 3 exhibits an interesting three-dimensional ‘honeycomb-like’ supramolecular network constructed by the stacking of [Co(2,2′-bipy)2(H2O)] units with one-dimensional channels, in which the [P4Mo6]-based polyoxometalate chains are located. The magnetic properties of compounds 2 and 3 are reported.

Ru3(CO)12 has been reacted with the compounds hex-1-en-3-yne [EtC≡CCH=CH2], 2-methyl-hex-1-en-3-yne [EtC≡CC(=CH2)CH3] and with 3(ethoxy-silyl)propyl isocyanate [(EtO)3Si(CH2)3NCO] and the compound tb [(EtO)3Si(CH2)3NHC(=O)OCH2C≡CCH2OC(=O)NH(CH2)3Si(OEt)3] in hydrocarbon solution. Some reactions in CH3OH/KOH solution (followed by acidification) have also been performed.
The main products of the reactions with ene-ynes are the clusters Ru3(CO)6(μ-CO)2L2 (L = C6H8, C7H10) and their demolition products, the “ferrole” Ru2(CO)6L2 complexes. One of the isomers of Ru3(CO)6(μ-CO)2L2, and Ru2(CO)6L2 (L = C7H10) have been reacted with vinyl-triethoxysilane [(EtO)3SiCH=CH2]: these reactions did not afford complexes containing new carbon–carbon bonds or triethoxy-silyl groups. Only polymerization
of vinyl-triethoxysilane occurred.
The reactions of Ru3(CO)12 with triethoxysilyl-propyl-isocyanate and tb (in the presence of Me3NO) lead to the same products, that is the isomeric complexes (μ-H)Ru3(CO)9[C=N(H)(CH2)3Si(OEt)3] with a “perpendicular” ligand (complex 3, as proposed on the basis of spectroscopic results) and (μ-H)Ru3(CO)9[HC=N(CH2)3Si(OEt)3] with a “parallel” ligand (complex 4, as confirmed by a X-ray analysis). The reaction pathways leading to these products are discussed. Complex 4 has been reacted with tetraethyl orthosilicate and the resulting material has been characterized. These reactions are part
of a study on the synthesis of inorganic-organometallic materials through sol–gel techniques.

Photolysis of a solution of Cp*RuCp (1) in CF3CO2H generates salt [CpRu(C5Me4CH2)]-(O2CCF3)(2 • O2CCF3). The reaction of compound 1 with oleum at 20 °C through the intermediate dication [η5-(CH2C5Me4)Ru(μ:η5,ν5-C5H4C5H5)Ru(C5Me4CH2)-η6]2+ leads to the triply charged cation η7CH2)2C5Me3Ru(μη5,η5-C5H4C5H4)Ru(C5Me4CH2)-η6]3+.

The 1,1’-dimethylvanadocene dichloride ((C5H4CH3)2VCl2) reacts in aqueous solution with various carboxylic acids giving two different types of complexes. The 1,1’-dimethylvanadocene
complexes of monocarboxylic acids (C5H4CH3)2V(OOCR)2 (R=H,CCl3, CF3, C6H5) contain two monodentate carboxylic ligands, whereas oxalic and malonic acids act as chelate compounds of the formula (C5H4CH3)2V(OOC-A-COO) (A=−, CH2). The structure of the (C5H4CH3)2 V(OOCCF3)2 complex was determined by single crystal X-ray diffraction analysis. The isotropic and anisotropic EPR spectra of all the
complexes prepared were recorded. The obtained EPR parameter values were found to be in agreement with proposed structures. 相似文献

The γ-hydroxypropyl-functionalised diiron dithiolate complex [Fe2(CO)6(μ-SCH2CH2CH2OH)2] is prepared upon thermolysis of Fe3(CO)12 and HO(CH2)3SH and further reaction with dppm (dppm = Ph2PCH2PPh2) affords [Fe2(CO)4(μ-dppm)(μ-SCH2CH2CH2OH)2]. From the reaction of Fe3(CO)12 with dppm(S2) a minor product is the tetrairon cluster, [{Fe2(CO)6(μ-SCH2CH2CH2OH)}2(μ4-S)], the mode of formation of which is unclear. It has been crystallographically characterised and adopts a μ4-S bridged double butterfly structure which is compared with other crystallographically characterised complexes of this type.

Cuboidal cluster aqua complex [Mo3(PdCl)S4(H2O)9]3+ in 4M HCl causes isomerization of (HO)2P(O)(H), (HO)P(O)(H)2, PhP(O)(OH)(H), and Ph2P(O)(H) into hydroxo tautomers P(OH)3, HP(OH)2, PhP(OH)2, and Ph2P(OH) which are stabilized by P coordination to the Pd atom in the cluster. The reactions were followed by 31P NMR and UV/Vis spectroscopy. Hypophosphorous acid H2P(O)(OH) in the presence of the cluster is rapidly oxidized into phosphorous acid; the reaction can be made catalytic. Coordination of PPh3 also takes place, giving [Mo3(Pd(PPh3))S4(H2O)5Cl4]0.5CH3OH3H2O, whose crystal structure was determined. 相似文献

The solid-state behaviour of two series of isomeric, phenol-substituted, aminomethylphosphines, as the free ligands and bound to PtII, have been extensively studied using single crystal X-ray crystallography. In the first library, isomeric diphosphines of the type Ph2PCH2N(Ar)CH2PPh2 [1a–e; Ar = C6H3(Me)(OH)] and, in the second library, amide-functionalised, isomeric ligands Ph2PCH2N{CH2C(O)NH(Ar)}CH2PPh2 [2a–e; Ar = C6H3(Me)(OH)], were synthesised by reaction of Ph2PCH2OH and the appropriate amine in CH3OH, and isolated as colourless solids or oils in good yield. The non-methyl, substituted diphosphines Ph2PCH2N{CH2C(O)NH(Ar)}CH2PPh2 [2f, Ar = 3-C6H4(OH); 2g, Ar = 4-C6H4(OH)] and Ph2PCH2N(Ar)CH2PPh2 [3, Ar = 3-C6H4(OH)] were also prepared for comparative purposes. Reactions of 1a–e, 2a–g, or 3 with PtCl2(η4-cod) afforded the corresponding square-planar complexes 4a–e, 5a–g, and 6 in good to high isolated yields. All new compounds were characterised using a range of spectroscopic (1H, 31P{1H}, FT–IR) and analytical techniques. Single crystal X-ray structures have been determined for 1a, 1b∙CH3OH, 2f∙CH3OH, 2g, 3, 4b∙(CH3)2SO, 4c∙CHCl3, 4d∙½Et2O, 4e∙½CHCl3∙½CH3OH, 5a∙½Et2O, 5b, 5c∙¼H2O, 5d∙Et2O, and 6∙(CH3)2SO. The free phenolic group in 1b∙CH3OH, 2f∙CH3OH, 2g, 4b∙(CH3)2SO, 5a∙½Et2O, 5c∙¼H2O, and 6∙(CH3)2SO exhibits various intra- or intermolecular O–H∙∙∙X (X = O, N, P, Cl) hydrogen contacts leading to different packing arrangements. 相似文献
