摘 要:<正>This paper deals with the structure of the YIII complex with aminopolycarboxylic acids, synthesis and structural determination of the complex (NH4)[YIII(edta)(H2O)3]·3H2O (edta = ethylenediaminetetraacetic acid). The crystal and molecular structures of the (NH4)[YIII(edta)(H2O)3]·3H2O complex have been determined by single-crystal X-ray structure analysis. The crystal of the complex (NH4)[YIII(edta)(H2O)3]·3H2O belongs to orthorhombic crystal system and fdd2 space group. The crystal data are as follows: a=1.944 1(9) nm, b= 3.545 9(18) nm, c = 1.219 6(6) nm, V= 8.407 (7)nm3,Z=16, Mr= 503.25, Dc= 1.590g.cm3, μ= 2.844 mm 1 and F(000) = 4 160. The final R and Ru are 0.048 6 and 0.133 2 for 3 388 (I>2σ(I)) unique reflections, respectively. The complex anion [YIII(edta)(H2O)3] has a pseudo-mono-capped square antiprismatic nine-coordinate structure in which the six coordinate atoms (two N and four O) are from an edta ligand and three water molecules coordinate to the central YIII ion directly.
