DINUCLEAR, TRINUCLEAR AND MIXED-METAL HEXANUCLEAR AGGREGATES OF VANADIUM - CRYSTAL-STRUCTURES AND PROPERTIES OF [NET4](3)[V2CL9], [PPH4](2)[V3OCL4(O2CC6H4SH)(5)] AND [NET4](4)[V2LI4O2CL4-(O2CC6H4S)(4)]

The reaction between [VCl3(thf)(3)] and Cl- provided a high-yield rout e to [NEt4](3)[V2Cl9] 1, which contains a [V-2(eta-Cl)(3)Cl-6](3-) fac e-sharing bioctahedron. The reaction of [VCl3(thf)3] with sodium 2-sul fanylbenzoate (mba(2-)) in he presence of water and PPh4Cl gave [PPh4] (2)[V3OCl4(Hmba)(5)] 2, whose anion contains a triangular [V-3(mu(3)-O )](7+) core. The reaction of [NEt4](2)[VOCl4] with H(2)mba and Li2S ga ve [NEt4](4)[V2Li4O2Cl4(mba)(4)] 3, whose anion contains two [VO(mba)] fragments bridged by a [Li4Cl4] unit. Compounds 1 and 2 are weakly an tiferromagnetically coupled with J = -13.4(4) and -3.2(1.6) cm(-1), re spectively ((H) over cap = -2JS(i)S(j) convention).
