Crystal engineering with a purine rare tautomer: structures and luminescence properties

Abstract

Cadmium interacts with purine nucleobases through N7 imino nitrogen and alters their amino–imino tautomeric equilibrium. Herein, we report unique crystallographic signatures and luminescence properties of cadmium complexes of <italic>N</italic>9-benzyl-<italic>N</italic>⁶-methoxyadenine exhibiting a variety of coordination numbers and spatial geometries.
