The potassium triaqua(ethylenediamine-tetraacetate)gadolinium (Ⅲ) pentahydrate, K[Gd(Edta)(H2O)3](5H2O, has been synthesized and structurally characterized. It crystallizes in orthorhombic, space group Fdd2 with a = 19.8851(6), b = 36.078(1), c = 12.2306(4)(A。), V = 8774.3(5) (A。)3, Z = 16, Dc = 1.904 g/cm3, Mr = 628.69, ( = 3.290 mm-1, F(000) = 5008, the final R = 0.0293 and wR = 0.0763 for 3314 observed reflections with I > 2((I). The Gd atom in the title compound is nine-coordinate through four O atoms and two N atoms in ethylenedi- amine-tetraacetate, and three O atoms of water.
