Résumé

A series of novel zirconium(IV) complexes, formulated as ZrCl3−n(acac)(OArI–V)n (where n =− 3; –OArI = OC6H4Cl-2, –OArII = OC6H4Cl-4, –OArIII = –OC6H3Cl2-2,4, OArIV = –OC6H3Cl2-2,6 and OArV = –OC6H2Cl3-2,4,6) were synthesized by reacting ZrCl3(acac) with corresponding substituted chlorophenols in separate experiments. The complexes were characterized by elemental analysis, molar conductance measurements, molecular weight determination, spectroscopic techniques (1HNMR and IR) and thermal gravimetric analysis. Based upon these studies, a triangular bipyramidal structure has been proposed. Acceptor properties of ZrCl3–n(acac)(OArI–V)n towards bidentate ligands such as 2,2’-bipyridyl and 1,10-phenanthroline allows the isolation of 1:1 addition compounds as shown by physicochemical, IR, and 1HNMR spectral studies. Keywords:Zirconium, acetylacetone, chlorophenol, reactivity and thermal analysis
