| Abstract: | New mixed-ligand complexes of lanthanides Ln(BA)2(NO3)(phen)]2(BA=ben-zoate, phen=1,10-phenanthroline) have been synthesized in aqueous solution of slight acidity and characterized by elementary analysis, IR and DTA-TG. Their ESR and fluorescence spectra were studied. The result of the crystal structure of Pr-complex shows that the complex is triclinic, space group P1, a=1.1007(8)nm, b=1.1177(3)nm, c=1.0687(4)nm, α=98.10(3)°, β=110.62(4)°, γ=84.80(4)°, Z=1, V=1.217(1) nm3, Dc=1.706 g/cm3, F(000)=620.00, μ(MoKα)=20.47cm-1. The crystaLIs consisted of a binuclear molecule. The coordination number of Pr3+is nine. The four BA ligands have two coordination modes: bidentate bridging and tridentate bridging. |
