Helicity of single-helical metal complexes, [(LZn3La)-Zn-1](3+) and [(LZn2La)-Zn-2](3+), was dynamically controlled by coordination of chiral carboxylate ions such as mandelate ion. Spectroscopic investigation indicated that two chiral carboxylate ions contribute to the dynamic helicity control. In addition, the coordination of the carboxylate ions resulted in a nonlinear response in the dynamic helicity control. (c) 2014 Elsevier Ltd. All rights reserved.
