| Abstract: The title compounds were synthesized and characterized by elemental analysis,thcrmo-analysis (TG-DTA),IR spectra,fluorescence spectra,molar conductivity and X-ray diffraction analysis.The X-ray structure analysis for the complex Na3[Eu(DPC)3]·14H2O (DPC=pyridine-2,6-dicarboxylatc) shows that it is a mononuclear complex,the crystal is triclinic,space group P1,with unit cell parameters: a= 1.1000(10),b=1.7268(22),c=1.0314(14)nm;α= 102.53(11)°,β= 107.05(8)°,γ=74.53(9)°;V=1.7845nm3;Z=2;De= l.80g.cm-1;μ= 18.9cm and R=0.073,Rw=0.085.The pyridine-2,6-dicarboxylic acid is a tridentatc ligand.The coordination number of europium is nine.The coordination polyhedron can be described as a distorted tri-capped trigonal prism. |
