Tris(5-bromo-2-methoxyphenyl)antimony (I) (yield, 85%) and tris(5-bromo-2-methoxyphenyl)bismuth (II) (yield, 81%) were obtained by reacting 5-bromo-2-methoxyphenyllithium with antimony(III) chloride and bismuth(III) chloride, respectively. According to X-ray diffraction data, the antimony atom in I is highly coordinated. The Sb-C bonds lengths are 2.160(1) Å, 2.163(1) Å, and 2.157(2) Å; the Sb…O distances are 2.985(1) Å, 3.051(1) Å, and 3.052(1) Å. The CSbC bond angles vary in the range of 92.19(6)°-94.52(6)°. Molecules of I are linked via Sb(A)…Br(B) intermolecular contacts (3.742(2) Å) to form polymer chains. 相似文献

The interaction of tris(4-fluorophenyl)antimony with chloroacetic, 4-nitrophenylacetic, and benzoic acids in diethyl ether in the presence of tert-butyl hydroperoxide has yielded tris(4-fluorophenyl)antimony dicarboxylates, their Sb atoms bearing distorted trigonal bipyramid coordination with the carboxylate ligands in the axial positions. The intramolecular contacts between Sb atom and carbonyl O atom are formed in the molecules of the products. Their crystal packing is determined by weak intermolecular hydrogen bonds of the H···F and H···O=C types. 相似文献

The reaction of 2-methoxyphenyllithium with SbCl3 affords tris(2-methoxyphenyl)antimony. Its treatment with equimolar amount of I2 results in stiborane (2-MeOC6H4)3SbI2, while heating with 2 equivalents of I2 leads to iodotris(2-methoxyphenyl)stibonium triiodide [(2-MeOC6H4)3SbI]+ [I3]– featuring halogen bonding in solid state. 相似文献

Tris(5-bromo-2-methoxyphenyl)bismuth bisbenzenesulfonate, which crystallizes from toluene in the solvate form (5-Br-2-MeOC6H3)3Bi(OSO2Ph)2 ? TolH (I), has been synthesized by the reaction between tris(5-bromo-2-methoxyphenyl)bismuth and benzenesulfonic acid in the presence of hydrogen peroxide (1: 2: 1 mol/mol/mol) in ether. A crystal contains two types of crystallographically independent molecules (a and b), in which bismuth atoms have a trigonal bipyramidal coordination to benzenesulfonate substituents in axial positions. The axial OBiO angle is 175.4(3)° (Ia) and 175.5(3)° (Ib), and the equatorial CBiC angles are 111.2(3)°, 122.0(4)°, 126.7(4)° (Ia) and 111.3(4)°, 123.3(3)°, 125.2(4)° (Ib). The Bi–C distances are 2.189(9), 2.198(9), 2.200(10) Å (Ia) and 2.198(9), 2.202(9), 2.209(9) Å (Ib). The Bi–O bond lengths are 2.274(8), 2.306(8) Å (Ia) and 2.248(8), 2.303(8) Å (Ib). Intramolecular contacts between the bismuth atom and the oxygen atoms of methoxy and sulfonate groups take place in molecules. 相似文献

(C6F5)3Sb has been found to react with interhalogens and halo-pseudohalogens, IX(X = Cl, Br, N3 and NCO), pseudohalogen (SCN), and elemental sulphur to give oxidative addition products (I–VI). (C6F5)3SbS(VI) may also be prepared by the reaction of (C6F5)3SbCl2 with H2S. Metathetical reactions of (C6F5)3SbCl2 with appropriate metallic salts yield covalent pentacoordinate disubstituted products (V, VII–XII) of the general formula, (C6F5)3SbY2 (Y = NCS, NCO, ?ONCMe2, ?ONCMePh O and p-NO2C6H4OCO). Treatment of (C6F5)3SbCl2 with aqueous NaN3 gives the binuclear oxo-bridge compound, [(C6F5)3SbOSb(C6F5)3](N3)2·(III) and (IV) are also accessible by displacement reaction of (I) or (II) with the corresponding metallic salt. Molecular weight, conductance measurements, and IR spectra on the new organoantimony(V) derivatives have been obtained.Reductive cleavage reactions of (C6F5)3SbS with hexaaryldileads, Ar6Pb2(Ar = Phenyl, p-tolyl) produce (C6F5)3Sb and the corresponding bis(triaryllead) sulphide but treatment of (C6F5)3SbX2(X = NCO, Cl) with Ar6Pb2 gave Ar4Pb and Ar2PbX2 together with (C6F5)3Sb.(C6F5)3SbCl2 and bis(triorganotin)sulphides undergo exchange of anionic groups. 相似文献

Tris(5-bromo-2-methoxyphenyl)antimony bis(2-nitrobenzoate) (I) is synthesized by the reaction of tris(5-bromo-2-methoxyphenyl)antimony with 2-nitrobenzoic acid in the presence of hydrogen peroxide (mole ratio 1: 2: 1). According to the X-ray diffraction data, the antimony atom has distorted trigonal bipyramidal coordination. The axial angle OSbO is 177.92(11)°, equatorial bonds CSbC are 109.23(16)°–128.31(16)°, and the Sb-O and Sb-C bond lengths are 2.095(3)–2.125(3) and 2.098(4)–2.113(4) Å, respectively. A specific feature of the structure of complex I is the presence of intramolecular contacts Sb...O(CH3) (2.992–3.175 Å along with the interactions Sb...O=C (3.039–3.117 Å). The structural organization in crystal is due to weak hydrogen bonds N-O...H-C, C=O...H-C, C-Br...H-C. 相似文献

A straightforward synthetic route to produce tris(methacrylato)chromium(III), Cr(O2C(CH3)C=CH2)3, by reacting sodium methacrylate with an aqueous solution of CrCl3 gave a blue microcrystalline powder, insoluble in most common solvents. Electronic spectroscopy (UV-Vis), electron paramagnetic resonance (EPR), Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS), were employed to characterize Cr(O2C(CH3)C=CH2)3. Morphology and elemental composition of this compound were determined using scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX), respectively. Spherical particles of approximately 2.5 µm in diameter were obtained. Thermal stability of the product was investigated via thermogravimetric analysis (TGA). The spectroscopic studies revealed that the coordination sphere around the chromium ion corresponds to a chelating bidentate carboxylate-Cr(III) complex. Thermal stability above 350°C, and spherical shape particles of few micrometers in diameter, suggest a potential application of this novel compound as a catalyst in oxidation reactions. 相似文献

The interaction of tris(4-fluorophenyl)antimony with copper(II) bromide in acetone has afforded tris(4-fluorophenyl)antimony dibromide; recrystallization of the product from ethanol has yielded the (4-FC6H4)3SbBr2·[(4-FC6H4)3SbBr]2O adduct. [(4-FC6H4)3SbCNS]2O oxide has been prepared from tris(4-fluorophenyl)antimony dibromide and potassium thiocyanate in aqueous-acetone solution. Antimony atoms in the molecules of the prepared compounds exhibited the distorted trigonal bipyramid coordination with the electron-accepting ligands in the axial positions. 相似文献

A series of five gold(I) halide complexes with the two isomeric methoxy-substituted triarylphosphines, tris(2-methoxyphenyl)phosphine [P(oanis)3], [AuP(oanis)3X] [for X = Cl, (1); X = Br, (2) and X = I, (3)] and tris(4-methoxyphenyl)phosphine [P(panis)3], [AuP(panis)3X] [for X = Br (4) and X = I (5)] have been synthesized and characterized by single crystal X-ray diffraction and solution 31P{1H} NMR spectroscopy. The structure determinations confirm the expected presence of linear two-coordination about the gold centres in all five complexes with bond distance and angle data typical of this type of compound [Au–P, 2.239(2)–2.259(3) Å; Au–Cl, 2.294(2) Å; Au–Br, 2.385(2)–2.402(2) Å; Au–I, 2.546(1)–2.554(1) Å; P–Au–X; 175.3(1)–180°]. All analogues except the iodo complex 5 crystallize with one complex molecule in the crystallographic asymmetric unit. The bromo and iodo complexes 2 and 3 constitute a trigonal isomorphous set while the bromo complex 4 is also isomorphous with the previously determined chloro complex [AuP(panis)3Cl]. The 2-methoxy analogues are stabilized by significant methoxy-O?Au interactions. 相似文献

A general method for the synthesis of carbon-centered tris(pentafluorophenyl)silyl derivatives (RSi(C6F5)3) by reaction of trichlorosilanes (RSiCl3) with pentafluorophenylmagnesium bromide was described. The crystal structures of obtained compounds were studied by X-ray diffraction analysis (7 structures). The peculiarities of crystal packing were analyzed by means of DFT calculations. 相似文献
