On the nature of the host–guest interaction between cyclam and 4-tert-butylbenzoic acid—a system pre-assembled for metal complex formation
Abstract
The host–guest interaction between cyclam and 4-tert-butylbenzoic acid has been investigated by NMR titration, X-ray diffraction, neutron diffraction and semi-empirical MO calculation; the product represents a system preassembled for metal-ion complexation.
