Interactions between poly(ethylene oxide)-based surfactants and transition metal alkoxides: Their role in the templated construction of mesostructured hybrid organic-inorganic composites

The interactions between PEO-based templates and metallic centres are key in the synthesis of mesostructured materials. In low-water-content media, strong chelation between metal centres and the non-ionic polar heads leads to polymer unfolding, and thus t

New chiral terpene-derived vanadatranes

The synthesis of three new chiral vanadatranes by reaction of oxovanadium(V) alcoholates with triethanolamine derivatives obtained from the terpenes (-)-β-pinene, (-)-limonene, and (-)-menthone is reported. Their structure is elucidated by NMR spectroscop

Vanadate complexes bearing an imidazolidine-bridged bis(aryloxido) ligand: Synthesis and solid state and solution structure

A new imidazolidine-bridged bis(aryloxido) ligand precursor (H 2L) [H2L = 2,2′-(imidazolidine-1,3- diylbis(methylene))bis(4-(1,1,3,3-tetramethylbutyl-2-yl)phenol)] was prepared in a relatively high yield (～60%) via a single-step Mannich condensation of 4-(1,1,3,3-tetramethylbutyl)phenol, ethylenediamine and paraformaldehyde at 2:1:3 molar ratio and characterized by chemical and physical techniques including X-ray crystallography. Reactions of H2L with [VO(OEt) 3] at 1:1 and 1:2 molar ratios in toluene afforded [V(L-κ3O,N,N,O)(O)(OEt)] (1) and [V2(μ-L- κ4O,N,N,O)(μ-OEt)2(O)2(OEt) 2] (2), respectively. Alcoholysis of 1 with EtOH enables elimination of one molecule of H2L and the formation of 2. Compounds 1 and 2 were characterized by IR and NMR spectroscopy as well as ES-MS experiments. The definitive molecular structure of 2 was provided by a single-crystal analysis and revealed its dinuclear nature, featuring two octahedral vanadium centres bridged by both OEt groups and the L ligand. The 51V, 1H and 13C NMR spectra as well as ES-MS showed that 2 does not stay intact in solution and undergoes dissociation to give 1 and [VO(OEt) 3].

Stucture, characterization and photoreactivity of monomeric dioxovanadium(V) Schiff-base complexes of trigonal-bipyramidal geometry

Five mononuclear cis-dioxovanadium(V) complexes of tridentate Schiff bases derived from salicylaldehyde and its derivatives and 8-aminoquinoline have been synthesized and characterized.Single-crystal X-ray analyses were performed with 1 and 2 (L1 and L2 denote the Schiff-base anions derived from salicylaldehyde or naphthaldehyde and 8-aminoquinoline).While the structure of 2 was refined to a final R = 0.074 (R' = 0.055), that of 1 was refined only to R = 0.134 (R' = 0.139) due to its poor diffraction quality.The complexes contain cis-oxo groups in the equatorial plane and a trigonal-bipyramidal geometry around the vanadium at which the Schiff base binds meridionally.Photoirradiation of these complexes in CH2Cl2 yielded chloride-bound VO(3+) species, as studied using absorption and (51)V NMR spectroscopy.These species are convertible back to the dioxovanadium(V) complexes upon addition of water to the photoirradiated solution.

Binding of L-histidine to vanadium. Structure of exo-[VO2{N-(2-oxidonaphthal)-His}]

The VIV complexes VO(H2O)L (2) (H2L is a Schiff base derived from o-hydroxynaphthalenecarbaldehyde and the amino acids glycine or phenylalanine) react with amines under aerobic conditions to VV complexes of the general composition VO(OH)L(amine) (5) (amine = imidazole, methylimidazole, pyrrole, pyridine, histidine, and histidine derivatives). With alcohols, the complexes VO(OR)L(ROH) (6) are formed. Histidine can also replace glycine in 2, forming the title compound 3 with the histidine moiety coordinating through one of the carboxylate-O moieties. Crystallographic data for 3: [VO2{O2CCH(CH2C3H4N 2)N=CHC10H6O}], space group C2; Z = 4, a = 13.7077(17) ?, b = 6.7390(6) ?; c= 17.1851(15) ?, β = 95.644(8)°, V = 1579.8(3) ?3, R = 0.0325, Rw = 0.0358, 3011 reflections (2916 with I > 2σ(I). The geometry around vanadium is square pyramidal. The two nitrogens of the imidazole unit are linked by intermolecular hydrogen bonds to the carboxylate oxygens and to the oxo group in the tetragonal plane. 3 models several of the active site features for vanadate-dependent haloperoxidases from marine brown algae.

Structural and spectroscopic characterization of dioxovanadium(V) complexes with asymmetric Schiff base ligands

A wide range of asymmetric Schiff base ligands containing primary amine functions can be prepared in one step and in high yield by the reaction of VO(OEt)3 with salicylaldehyde and the appropriate diamine. The resulting VO2L complexes contain tridentate ligands with phenolate, imine, and amine coordination to the dioxovanadium(V) complex ion. An X-ray structure of one compound ([VO2(1,2-pnSAL)], 5A, where 1,2-pnSAL = 1(N-salicylideneamino)-2-aminopropane) demonstrates that it is a dimer in the solid state with a V2O4 core. However, when dissolved in DMSO, this material dissociates into monomers. Proton NMR spectroscopy reveals that the second isomer, 5B [VO2(1-amino-2(salicylideneamino)propane], is prepared in the process, but to a much lesser extent than 5A (85:15). The reactivity of VO2(enSAL) [enSAL = 1-(N-salicylideneamino)-2-aminoethane] with peroxides in neutral, basic, and acidic media is discussed. Significantly, the reported synthetic methodology does not yield successful VO2(1-(N-salicylideneamino)-3-aminopropane) [VO2(1,3-pnSAL)]. Instead, the V(IV) complex VO(SALPN)DMSO (8) is isolated and has been characterized structurally (SALPN = 1,3-bis-(N-salicylideneamino)propane). Although VO(SALPN)DMSO and VO(SALEN) have markedly different solution spectra, their reactivity with coordinating and noncoordinating acids are very similar.
