Crystal structure and chiroptical spectra of sodium tetrakis (+)-hfbc Pr(III) complex

Abstract The X-ray crystal structure of tetrakis (+)-hfbc Pr(III) complex, Na[Pr((+)-hfbc) 4 ]·CH 3 CN, was compared with that of the corresponding Na–La complex with a pseudo-achiral dodecahedron, and the solution CD spectra were also discussed in the 4f–4f transition in consideration of the exciton CD couplet showing Δ-SAPR-8 configuration in CHCl 3 .
