The title complex ([SmN(CH 2COO) 3(H 2O) 2]·H 2O, M r =392.52) has been prepared from Sm(ClO 4) 3 and NH 2(CH 2COO) 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) , V=2211.9(5) 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 Sm 3+ is nine coordinated and the coordination polyhedron is a distorted, tricapped trigonal prism. The whole structure can be characterized as a two dimensional network.
