(AsPh4)2[(μ‐N2S2) (VCI5)2] Synthese, IR‐Spektrum und Kristallstruktur

Abstract: Bei der Reaktion von VCl4und S3N2Cl2 in CCl4‐lösung entsteht ein festes Produktgemisch; durch Zusatz von AsPh4Cl in CH2Cl2‐Lösung kann aus diesem die Titelverbindung herausgelöst werden. Sie kann auch aus AsPh4VCl5 mit Trithiazylcholorid in CH2Cl2‐Lösung erhalten werden. Die IR‐Spektren von (AsPh4)2[(μ‐N2S2)(VCl5)5] (schwarze Kristallplättchen) und von AsPh4VCl5 (braune Nadeln) werden mitgeteilt. Die Kristallstruktur von (AsPh4)2[(μ‐N2S2)(VCl5)2] wurde durch röntgenbeugung ermittelt. Es kristallisiert monoklin… Show more

“…Nevertheless, the formulated anionic component of 4 , namely [VCl 5 ] - , has been characterized twice previously in the solid state in crystals of [PPh 4 ] 2 [V 2 Cl 9 ][VCl 5 ]·CH 2 Cl 2 and in crystals of [PCl 4 ][VCl 5 ] . Interestingly, [PCl 4 ][VCl 5 ], like [NO][VCl 5 ], is a black volatile solid. , The [VCl 5 ] - anion can also be formed by reacting 1 equiv of [AsPh 4 ]Cl with VCl 4 …”

“…The first metallacyclothiazene ([VCl 2 (N 3 S 2 )] ∞ ) could be synthezised by Roesky et al in 1983. 16 This synthesis has been optimized by Dehnicke et al 17 and transferred to other transition metals (molybdenum 18 and tungsten 19 ). These compounds can be derived formally from the [S 3 N 3 ]ion by substitution of a sulfur atom by an isoelectronic transition metal fragment.…”

“…This charge separation gives evidence to the suggestion that the electronic structure of [S 3 N 3 ]is similar to that of cyclophospazenes. 16,17 is a polymer. For the salts [AsPh 4 ] + [MCl 4 (N 3 S 2 )] -, M ) Mo and W crystal structures are available.…”
