  led to the formation monoaqua ternary complexes. Even under these conditions, the average relaxivity remains higher or similar than most currently used contrast agents. Only hydrogen carbonate interacts strongly with the complexes and coordinates in a bidentate mode by displacing both water molecules to induce a twofold decrease in the relaxivity. Both complexes interact with serum albumin to form a
