of its Gd(III) complex Gd-L1 are reported. The Gd(III) complex of the diethylenetriaminepentaacetate analogue of the ligand described here (L2) is the MRIcontrastagent MS-325. The effect of converting an acetate to a methyl group on metal-ligand stability, hydration number, water-exchangerate, relaxivity, and binding to the protein human serum albumin (HSA) is explored. The complex Gd-L1 has two
