Syntheses of some cyclopentadienyl[hydrotris(pyrazol-1-yl)borato]bis(aryloxo)zirconium(IV) complexes and the X-ray crystal structure of [Zr(η-C5H5){χ3-HB(pz)3}(OC6H4Ph-2)2]

Abstract

The complexes [M(C5H5){HB(C3N2H3)3}Cl2](M = Zr or Hf) have been prepared by the reaction of [M(η5-C5H5)2Cl2] with the protonated form of the hydrotris(pyrazol-1-yl)borate ligand. The reduction potential of [Zr(C5H5){HB(C3N2H3)3}Cl2] in CH2Cl2 solution is –1.59 V (SCE) which is comparable to that of [Zr(η5-C5H5)2Cl2]. The zirconium complex reacts with phenols to produce the air and moisture stable complexes [Zr(C5H5){HB(C3N2H3)3}(OC6H4Z)2](Z = H, 4-OMe, 4-NO2 or 2-Ph). The molecular structure of [Zr(C5H5){HB(C3N2H3)3}(OC6H4Ph-2)2] has been determined by X-ray diffraction methods and contains and η5-cyclopentadienyl ligands, two symmetrically inequivalent phenoxide ligands and a κ3-HB(C3N2H3)3 ligand.
