Abstract: | 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 C3v (cis-configuration). It is probable, that in cations including a NH-group a decrease of the symmetry towards Cs arises by means of the hydrogen bondings. |
