The cluster[(
-C5Me5)V(
-Cl)2]3was synthesized from VCl3(thf)3 andBun3SnC5Me5.Itwas oxidized by O2 to give(-C5Me5)VCl2(O), and byNaN3 to give[(-C5Me5)VCl(-N)]2.X-raydiffraction showed that[(-C5Me5)V(-Cl)2]3had an equilateral triangle of vanadium atoms(mean V-V 3.367 (2) Å), with each edge of the triangle symmetricallybridged by two chlorineatoms. The cluster contains six core electrons. The cluster[(-C5Me5)V(-Cl2]3had amagnetic moment of 2.92 B at room temperature and showedantiferromagnetic behavior.
