✦ Synopsis

In the title complex, [Cu(C 4 H 6 N 2 O 3 )(C 5 H 5 N 5 )(H 2 O)], 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][97][98][99].

The tridentate Schiff base ligand derived from the condensation of salicylaldehyde and dl-tyrosine, in the presence of pyridine, forms a square-pyramidal ®ve-coordinate Cu complex, [Cu(C 16 H 13 NO 4 )(C 5 H 5 N)(H 2 O)], with a water molecule occupying the apical site.
