A choice selection : A dynamic combinatorial library of oligonuclear coordination compounds is formed from a flexible tris(catechol) ligand with titanium( IV ) ions in the presence of lithium carbonate or potassium carbonate. A trinuclear complex ( 1 ) can be isolated by crystallization from DMF. In contrast, well‐defined mononuclear ( 2 ) compounds are obtained by addition of Na + as a template, and tetranuclear compounds ( 3 ) are isolated by changing the solvent to DMSO.
