Reaction of VC14 with (Me3Si)2S in CH2C12 yields an insoluble product with the approximate composition VSC12. Its reaction with PPh4Cl in CH2Cl2 affords (PPh4)3[V2Cl9] · 7 CH2Cl2, whereas PPh4[VOCl4] is formed in the presence of oxygen. According to an X-ray crystal structure analysis, (PPh4)3[V2Cl9] · 7 CH2Cl2 contains [V2C19]3- ions having two face-sharing coordination octahedra but no significant metal-metal bonding (V-V distance 327.5 pm). Crystal data: a = 1386.4(7), b = 1405.6(7), c = 2710(2) pm, α = 95.800(5), β = 95.370(5), γ = 118.11(3)°, triclinic, Ρ 1̄, Ζ = 2; R = 0.066 for 8779 observed reflexions. PPh4[VOCl4] is isotypic with AsPh4[VOCl4] and contains tetragonal-pyramidal [VOCl4]- ions; tetragonal, P4/n, Z = 2, a = 1264.5(2), c = 772.0(2) pm; R = 0.050 for 654 observed reflexions.
