Synthese und Kristallstruktur von [N(PPh3)2][VCl3(N3S2)]·C7H8 / Synthesis and Crystal Structure of [N(PPh3)2][VCl3(N3S2)]·C7H8

Abstract

Abstract [N(PPh3)2][VCl3(N3S2)]·C7H8 is formed by the reaction of VCl2 (N3S2) with excess PPh3 in CH2C12 and subsequent treatment of the reaction mixture with toluene, as well as by the reaction of VCl2(N3S2) with [N(PPh3)2]Cl in CH2Cl2 in the presence of toluene. The compound forms red crystals, which have been characterized by IR spectroscopy. The crystal structure was determined by X-ray diffraction (1433 observed, independent reflexions, R = 0.070). Crystal data: mono-clinic, space group Cc, Z = 4, a = 994.1, b = 2148.0, c = 2055.2 pm, β = 90.03°. The compound consists of [N(PPh3)2]⊕ cations and [VCl3(N3S2)]⊖ anions, in which the vanadium atom is five-coordinated by threee chlorine atoms and two nitrogen atoms, and is part of a planar VN3S2 ring.
