    NMR study of the [VO(O2)2F]2- ion in solution: Synthesis, vibrational spectra and crystal structure of [NH3CH2CH2NH3][VO(O2)2F]

  • Original language description

    The presence of the [VO(O2)2F]2- ion in an aqueous solution gives rise to a doublet (delta = -714 ppm, JVF = 163+/-3 Hz) in the 51V NMR, and a multiplet (delta = -160 ppm, Delta nu 1/2 = 1163 Hz) in the 19F NMR spectrum. The formation of this species isenhanced in formamide solutions. The ethane-1,2-diammonium(2+) fluorooxodiperoxovanadate, [NH3CH2CH2NH3][VO(O2)2F], was prepared from aqueous solution and characterized by elemental analysis, and IR and Raman spectroscopies. The complex crystallizes in the orthorhombic space group Pbca with eight formula units in a cell of dimensions: a = 9.2690(4), b = 8.8321(5) and c = 16.7605(8) A. The complex anion has a rare pentagonal pyramidal structure with a very weak intermolecular interaction d(V...O) = 2.8730(12) A between the vanadium atom and the double-bonded oxygen atom from the adjacent anion.

    NMR studie [VO(O2)2F]2- iontu v roztoku: Syntéza, vibrační spektra a krystalová struktura [NH3CH2CH2NH3][VO(O2)2F]

  • Czech description

    Přítomnost [VO(O2)2F]2- iontu ve vodném roztoku dává vzniknout dupletu (delta = -714 ppm, JVF = 163+/-3 Hz) při 51V NMR a multipletu (delta = -160 ppm, Delta nu 1/2 = 1163 Hz) v 19F NMR spektru. Vznik takovýchto produktů v roztoku je podpořen přítomnostíformamidu. Ethan-1,2-diammonium(2+) fluorooxodiperoxovanadičnanový komplex, [NH3CH2CH2NH3][VO(O2)2F], byl připraven z vodného roztoku a charakterizován element. analýzou a IR + Raman. spektroskopií. Komplex krystaluje v orthorhombické prostorové grupě Pbca s 8 vzorcovými jednotkami v krystalové mřížce s parametry a = 9.2690(4), b = 8.8321(5) a c = 16.7605(8) A. KOmplexní anion má neobvyklou pentogonálně pyramidální strukturu s velmi slabou mezimolekulární interakcí d(V...O) = 2.8730(12) A mezi atomen vanadu a dvojnou vazbou vázaným O atomem ze sousedního iontu.
