Die Kristallstrukturen von (NH4)2[ReCl6], [ReCl2(CH3CN)4]2[ReCl6] · 2CH3CN und [ReCl4(18‐Krone‐6)]

Abstract: Braune Einkristalle von (NH4)2[ReCl6] entstehen durch Reaktion von NH4Cl mit ReCl5 in einer Diethylethersuspension. [ReCl2(CH3CN)4]2[ReCl6] · 2CH3CN kristallisiert als braune Kristallplättchen aus einer Lösung von ReCl5 in Acetonitril. Leuchtend grüne Einkristalle von [ReCl4(18‐Krone‐6)] entstehen durch Reaktion von 18‐Krone‐6 mit ReCl5 in einer Dichlormethansuspension. Die drei Rhenium‐Verbindungen werden durch ihre IR‐Spektren und durch Kristallstrukturanalysen charakterisiert. (NH4)2[ReCl6]: Raumgruppe Fm3m… Show more

“…The spectra consist of only one narrow singlet for the coordinated acetonitrile ligands (δ = 65.5 ppm [ 5 ] + ; δ = 60.0 ppm [ 6 ] + ; δ = 54.7 ppm [ 7 ] + ). The crystal structure of [ 5 ]­(ReCl 6 ) 1/2 is known in the literature, but further spectroscopic analyses have not been reported . The reported crystal structure aligns very well with the values found for [ 5 ]­BPh 4 .…”

“…Therefore, the structures of this kind of Schiff bases are relevant due to the possibility of finding them in the solid state and/or in solution as keto-amine or phenol-imine tautomers, and their connections with photochromism and thermochromism. In the solid state, salicylaldimine Schiff bases tend to form (N···H-O) or (N-H···O) types of hydrogen bonding, respectively [4]. In many cases in solution, both types of hydrogen bonds have been observed indicating phenol-imine, O-H· · ·N, keto-amine, O···H-N tautomerism [5].…”
