Zur Koordinationschemie des Rhenium(VII). V. Trioxo-trichlororhenate(VII) mit stickstoffhaltigen Kationen

Coordination Chemistry of Rhenium(VII). V. Trioxotrichlororhenates(VII) with Nitrogen-containing Cations Complex compounds of the composition A₂ReO₃C₃ were obtained by reaction of ReO₃Cl with the chlorides ACl (A = (CH₃)₄N⁺, (C₂H₅)₄N⁺, PyH⁺, ChinH⁺ (CH₃)₃NH⁺ and CH₃Py⁺) in inert solvents. It has been decuced from the Re? O stretching vibrations of the IR spectra, that the anion ReO₃Cl in connection with the cations (CH₃)₄N⁺ resp. (C₂H₅)₄N⁺ has the symmetry C_3v (cis-configuration). It is probable, that in cations including a NH-group a decrease of the symmetry towards C_s arises by means of the hydrogen bondings.
