The highest water exchange rate ever measured for a Gd(III) chelate

Abstract :

The complex [Gd(L)(H2O)](3-) (H6L = N,N-’-bis(6-carboxy-2-pyridylmethyl) ethylenediamine-N,N’-methylenephosphonic acid) displays the highest water exchange rate ever measured for a Gd(III) chelate (k(ex)(298) = 8.8 x 10(8) s(-1)), which is attributed to the flexibility of the metal coordination environment.
