DOIAbstract
The coordination-driven self-assembly of an anthracene-functionalized ditopic pyridyl donor and a tetracene-based dinuclear Ru(II) acceptor resulted in an interlocked metalla[2]catenane, [M<sub>2</sub>L<sub>2</sub>]<sub>2</sub>, in methanol and a corresponding monorectangle, [M<sub>2</sub>L<sub>2</sub>], in nitromethane. Subsequently, guest template, solvent, and concentration effects allowed the self-assembly to be reversibly fine-tuned among monorectangle and catenane structures
