The title complex ([SmN(CH2COO)3 (H2O)2 ]· H2O, Mr = 392.52)has been prepared from Sm(ClO4)3 and NH2 (CH2COO)3Na in aqueous solution. The crystal structure of the complex was determined by X-ray diffraction method. The crystal belongs to the orthorhombic system with space group Pbca, a = 8. 110(1), b =13.120(2), c=20.788(2)(A。), V=2211.9(5)(A。)3, Z=8, F(000)=1512, μ=5. 349 mm- 1 R = 0. 0182 and wR = 0. 0385 for 1909 observed reflections with Ⅰ＞2σ (Ⅰ). The Sm3+ is nine-coordinated and the coordination polyhedron is a distorted, tricapped trigonal prism. The whole structure can be characterized as a two-dimensional network.
