A novel macrocyclic zirconocene(iv) aromatic selenite [(CpZr)8L16]·2(Cp4Zr2(μ-O)Cl2) (complex 1) (Cp = cyclopentadienyl anion; L = 4-fluorobenzeneseleninic acid) was prepared by the reaction of bis(cyclopentadienyl)zirconium dichloride with 4-fluorobenzeneseleninic acid and characterized by elemental analysis, infrared spectroscopy, 1H, 13C NMR spectroscopy, ESI-MS, XRD and X-ray diffraction.
