Abstract

Reactions of dichlorobis(cyclopentadienyl)zirconium(IV) with pyridinedicarboxylic acids viz. quinolinic acids (QAH2), 2,4-pyridine dicarboxylic acid (PAH2), isocinchomeronic acid (IAH2), cinchomeronic acid (CAH2) and dinicotinic acid (DAH2) were carried out in different stoichiometric ratios. Complexes of the type Cp2Zr(QAH)Cl, Cp2Zr(QAH)2, Cp2Zr(PAH)Cl, Cp2Zr(PAH)2, Cp2Zr(IAH)Cl, Cp2Zr(IAH)2, Cp2Zr(CAH)Cl, Cp2Zr(CAH)2, Cp2Zr(DAH)Cl and Cp2Zr(DAH)2 were obtained. These new complexes were characterized on the basis of their elemental analyses, electrical conductance, magnetic moment and spectral data.
