Abstract: In the title complex, [Cu(C₄H₆N₂O₃)(C₅H₅N₅)(H₂O)], the Cu^II atom is five-coordinated in a square-pyramidal geometry by a tridentate glycylglycinate ligand (glygly), an N atom from an adenine ligand (Hade) and a water molecule in the apical position. The Hade coordination is reinforced by an intramolecular hydrogen-bonding interaction. A much lower precision structure has already been determined using intensities collected by the film method [Tomita, Izumo & Fujiwara (1973). Biochem. Biophys. Res. Commun. 54, 96-99].
