Abstract

The left-handed isomer of the helical complex [LZn3La(OAc)3] was spontaneously enriched from 50 ∶ 50 to 87 ∶ 13 when the quasiracemate crystals were dissolved. The invertible helicity of [LZn3La(OAc)3] (global chirality) helps the quasiracemate formation and the fixed point chirality of the R,R-cyclohexanediamine moiety (local chirality) effectively controls the global chirality in solution.
