Isolation of a uranyl amide by "ate" complex formation.
The uranyl amide [{Li(DME)}(2)Cl][Li(DME)][UO(2)(NC(5)H(10))(3)](2) has been synthesised and structurally characterised. Its stability is attributed to the saturation of the uranyl coordination sphere by "ate" complex formation.
متن کاملPorous gold nanobelts templated by metal-surfactant complex nanobelts.
Unique, porous gold nanobelts consisting of self-organized nanoparticles were synthesized in a high yield by morphology-preserved transformation from metal-surfactant complex precursor nanobelts formed by a bolaform surfactant dodecane-1,12-bis(trimethylammonium bromide) (N-C(12)-NBr(2)) and HAuCl(4). It was revealed that the precursor nanobelts of the stoichiometric N-C(12)-N(AuCl(4))(2) compl...
متن کاملThe first cyclopentadienyl complex of uranyl.
The U(IV) linear pentacyano metallocene [U(C(5)Me(5))(2)(CN)(5)][NEt(4)](3) reacted with 2 molar equivalents of pyridine N-oxide in THF or acetonitrile to give the U(VI) complex [UO(2)(C(5)Me(5))(CN)(3)][NEt(4)](2), the first uranyl species containing the cyclopentadienyl ligand; the crystal structure revealed that the steric effects of the (C(5)Me(5)) ligand force the {UO(2)}2+ ion to deviate ...
متن کاملA Polarographic Study of Uranyl-Salicylate and Uranyl-Phthalate Complex Formation in Acidie Solutions
The d. c. and a. c. polarography and cyclic voltammetry were applied to the study of uranyl-salicylate and uranyl-phthalate complexes. The study was limited to the pH range <5, because insoluble uranyl-hydroxydes are formed above this pH value. Uranyl-salicylate and -phthalate are irreversibly reduced. The electrode process is preceded by the chemical reaction of the complex with protons. By th...
متن کاملSynthesis and reactivity of a uranyl-imidazolyl complex.
Treatment of [UO(2)(Ar(2)nacnac)Cl](2) with 4 equiv. of Li(C(4)H(5)N(2)) results in the formation of a rare uranyl organometallic complex [Li(MeIm)][UO(μ-O)(Ar(2)nacnac)(μ-C,N-C(4)H(5)N(2))(2)] (2), in moderate yield. Reaction of 2 with 1 equiv. of MCl(2) (M = Fe, Co) yields the bimetallic complexes [MCl(MeIm)][UO(2)(Ar(2)nacnac)(μ-N,C-C(4)H(5)N(2))(2)] (M = Fe, 3; M = Co, 4).
