Summary: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.
