 Title    Cyclothiazeno-Vanadiumdibromid, VBr2(N3S2) Cyclo-Thiazeno Vanadium Dibromide, V B r2(N 3 S2)  
 Abstract    V B r 2(N 3S2) was synthesized by reaction o f VC12(N 3S2) with M e 3SiBr. It reacts with PPh4B r in dibromomethane solution to form (P P h 4) 2[V B r 3(N 3S2) ] 2. The compounds were characterized by their IR and 51V N M R spectra. The crystal structure o f V B r 2(N 3S2) was determined by X-ray diffraction (2060 reflexions, R = 0.114). Crystal data: triclinic, space group P I , a — 586.4, b = 794.2, c — 744.6 pm, a = 89.25, ß = 108.58, y — 99.67°, Z = 2. The vanadium atoms form planar, six-membered rings with the N 3S2 groups, with short V N distances (172 and 185 pm). Bromine-bridged dimers are associated via V —N links to form chains in a similar way as in some tetrahalides. The structure is similar to that o f VC12(N 3S2), but the chains are rotated by 17° along their axes.
