Abstract
Two rare earth heteropolymetalates K9GdW10O36 and K-11[Gd(PW11O39)(2)] have been synthesized and characterized by IR and elemental analysis. Their sta bility has been studied by TG - DTA. The TG - DTA analysis show that both c omplexes are of good thermal stability. Their relaxivity in D2O is 6.89 and 5.27 mmol(-1).s(-1) respectively. Interaction with BSA has also been inves tigated. The results indicate that the two rare earth heteropolymetalate ma y be potential contrast agent for MRI.
