Synthesis and Structure Determination of Lanthanum Complex with β-Alanine {[La2（β-ala）6（H2O）4]（ClO4）6·H2O}n
【Abstract】 The complex, {[La2(β ala)6(H2O)4](ClO4)6·H2O}n, was synthesized in aqueous solution and its crystal structure was determined by X ray diffraction method .The crystal is triclinic with space group of <IMG SRC="IMAGE/04260088.JPG"HEIGHT=11 WIDTH=12>.The cell parameters are a=0.946(1)nm, b=1.2917(1)nm, c=2.1726(3)nm,α=76.79(1)°, β=80.85(1)°,γ=83.35(1)°, V=2.5429(5)nm3, Z=2, Dc=1.958g·cm-3.The complex is an one dimensional infinite chain. The coordination number of lanthanum ion is nine, forming a distorted tricapped trigonal prism.
