Coordination Chemistry of Rhenium(VII). V. Trioxotrichlororhenates(VII) with Nitrogen-containing CationsComplex 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 ReO3Cl32- 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.
Notes:
Durch Umsetzung von ReO3Cl mit den Chloriden ACl (A —(CH3)4N+, (C2H5)4N+, PyH+, ChinH+, (CH3)3NH+ und CH3Py+) in inerten Lösungsmitteln werden Komplexe der Zusammensetzung A2ReO3Cl3 erhalten. Aus den Re—O-Valenzschwingungen der IR-Spektren ergibt sich, daß das ReO3Cl32--Anion in seinen Salzen mit (CH3)4N+ und (C2H5)4N+ C3v-Symmetrie (cis-Konfiguration) aufweist. Bei Kationen, die eine NH-Gruppe enthalten, tritt wahrscheinlich infolge von Wasserstoffbrückenbindungen Symmetrieerniedrigung nach Cs ein.
