Dichloro(tetrahydrofuran-O)[tris(1-pyrazolyl-N²)borato]vanadium(III)

The title compound, [HB(pz)₃]VCl₂(thf) or [VCl₂(C₉H₁₀BN₆)(C₄H₈O)] (pz = pyrazolyl, thf = tetrahydrofuran), is an analogue of the unknown [eta]⁵-CpVCl₂ (Cp = unsubstituted cyclopentadienyl). The pyrazolyl complex was prepared from VCl₃(thf)₃ and K[HB(pz)₃]. The molecule adopts a structure comparable to the piano-stool arrangement of a half-sandwich complex.
