The reaction of Cp2ZrCl2 with 3,5-dicholorosalicylic acid in a CH2Cl2–Et2O system containing HCl (1.0 mol L−1), gives a cage half-sandwich cyclopentadienyl–zirconocene compound, [(CpZr)6(μ-O2C-C6H2Cl2-2-O)9(OH2)3]·H2O (1). The crystal structure of 1 shows a twisted tripyramidal prism cage structure with one water molecule in the cage’s cavity. In the cage, the dianionic, substituted salicylate ligands adopt a bridging chelate μ2-(O, O′, O″) coordination mode.
The cage half-sandwich cyclopentadienyl-zirconium compound, [(CpZr)6(μ-O2C–C6H2Cl2–2-O)9 (OH2)3]·H2O (1), was synthesized and characterized. The X-ray diffraction analysis shows that a dianionic, substituted salicylate ligand adopts a bridging chelate μ2-(O, O′, O″) coordination mode and the twisted tripyramidal prism cage structure with one water molecule in the cage’s cavity.Figure optionsDownload as PowerPoint slide
