All three structures are characterized by a planar three-coordinate zinc in a distorted trigonal arrangement that is coplanar with the pyrimidine ring and embedded in a rather rigid structure.

WebAnnular tautomerism is a type of prototropic tautomerism where a proton can occupy two or more positions of a heterocyclic system. for example, 1H- and 3H-imidazole; 1H-, 2H- and 4H- 1,2,4-triazole; 1H- and 2H- isoindole.
