The 1,3‐Dimethylcyanurate Ion as an Ambident Ligand 1,3‐Dimethyl‐2,4,6‐trioxo‐1,3,5‐triazin ( 7 ), (1,3‐dimethylcyanuric acid, DMCH), obtained from the thermolysis of methyl urea, is deprotonated with lithium ethylate. In the resulting dinuclear complex [(DMCLi) 2 ·4 H 2 O] ( 8 ), the heterocyclic anions are linked to the lithium centres with oxygen atoms as its enolate form. In the corresponding silver complex [(DMCAg) 2 ·en] ( 10 ), (en = ethylendiamine), N ‐coordination of the ligand is observed. The crystal structures of 7 , 8 , and 10 reveal the presence of intermolecular hydrogen bonds.
