Abstract

The reactions of [ZrCl₂(thf)(η-C₈H₈)] with K[H₂B-(pz)₂], K[HB(pzMe₂)₃], and Na[H₂B(mt)₂] (pz = pyrazolyl, mt = methimazolyl) provide the complexes [Zr(κ²-L)Cl(η-C₈H ₈)] (L = H₈B(pz)₂, HB(pzMe₂) ₃, H₂B(mt)₂). In each case the metal is electronically unsaturated (16 electrons), despite the capability, in principle, of each of the ligands "L" to increase the metal coordination number. The only product isolated so far from the corresponding reaction with K[H ₂B(pzMe₂)₂] is, however, the organometallic oxide cluster [Zr₄(μ-O)₄(μ-Cl)₂Cl ₂(η-C₈H₈)₄].
