The title compound, [HB(pz)3]VCl2(thf) or [VCl2(C9H10BN6)(C4H8O)] (pz = pyrazolyl, thf = tetrahydrofuran), is an analogue of the unknown 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.
