Abstract:	We report the synthesis of two new three-dimensional coordination polymers (CPs) based on Co(II), adenine, and aromatic tetracarboxylate linkers. Adenine exhibits bidentate binding modes in both CPs, coordinating through the N<inf>3</inf> and N<inf>9</inf> sites in a first compact CP and through the more rare N<inf>3</inf> and N<inf>7</inf> sites in a second open, flexible, and H<inf>2</inf>O-responsive CP. These differences together with an analysis of the extended coordination structures made of adenine reported in the Cambridge Structural Database illustrate the rich coordination versatility of adenine as a building block for CPs. Although the latter CP is nonporous to N<inf>2</inf> or CO<inf>2</inf>, it shows a reversible and detectable color change from pink to purple, and vice versa, upon hydration and dehydration, respectively.
