The reaction between [VCl3(thf)3] and Clâ provided a high-yield route to [NEt4]3[V2Cl9] 1, which contains a [V2(µ-Cl)3Cl6]3â face-sharing bioctahedron. The reaction of [VCl3(thf)3] with sodium 2-sulfanylbenzoate (mba2â) in the presence of water and PPh4Cl gave [PPh4]2[V3OCl4(Hmba)5] 2, whose anion contains a triangular [V3(µ3-O)]7+ core. The reaction of [NEt4]2[VOCl4] with H2mba and Li2S gave [NEt4]4[V2Li4O2Cl4(mba)4] 3, whose anion contains two [VO(mba)] fragments bridged by a [Li4Cl4] unit. Compounds 1 and 2 are weakly antiferromagnetically coupled with J = â13.4(4) and â3.2(1.6) cmâ1, respectively (Ĥ = â2JSiSj convention).
