Chiral zirconium(IV) double cage sandwich complex <b>Zr(1)<sub>2</sub></b> has been synthesized in one step from porphyrin cage <b>H<sub>2</sub>1. Zr(1)<sub>2</sub></b> was obtained as a racemate, which was resolved by HPLC and the enantiomers were isolated in >99.5 % ee. Their absolute configurations were assigned on the basis of X-ray crystallography and circular dichroism spectroscopy. Vibrational circular dichroism (VCD) experiments on the enantiomers of <b>Zr(1)<sub>2</sub></b> revealed tha ...[more]
