The first elucidation of the structure of a metal complex of ATP has been carried out on [Cu(ATP)(phen)] 2 ·7H 2 O. This complex could be isolated at pH = 2.8. The two independent Cu atoms exhibit highly distorted octahedral coordination: The two N atoms of the phenanthroline and two phosphate O atoms are equatorial ligands, two further phosphate O atoms are axial. Complexes of this type are interesting as models of ternary enzyme‐M 2+ ‐ATP complexes which participate in enzymatic phosphate transfer.
