Abstract

The cluster [(eta-C5Me5)V(mu-Cl)(2)](3) was synthesized from VCl3(thf)(3) and (Bu3SnC5Me5)-Sn-n. It was oxidized by O-2 to give (eta-C5Me5)VCl2(O), and by NaN3 to give [(eta-C5Me5)VCl(mu-N)](2). X-ray diffraction showed that [(eta-C5Me5)V(mu-Cl)(2)](3) had an equilateral triangle of vanadium atoms (mean V-V 3.367 (2) Angstrom), with each edge of the triangle symmetrically bridged by two chlorine atoms. The cluster contains six core electrons. The cluster [(eta-C5Me5)V(mu-Cl-2](3) had a magnetic moment of 2.92 mu(B) at room temperature and showed antiferromagnetic behavior.
