Crystal Structure of Complex Tris(4,4,4-trifluoro-1-phenyl-1,3-butanedione)(1,10-phenanthroline) Europium(III)

【Abstract】 The complex Eu(btfa) 3(phen) (btfa=4,4,4 trifluoro 1 phenyl 1,3 butanedione, phen=1,10 phenanthroline) has been prepared and characterized by elemental analysis, IR and UV spectroscopies. The crystal and molecular structures of the complex have been determined by X ray diffraction analysis. It belongs to the monoclinic crystal system, space group P 2 1/ c with a =0 9700(2) nm, b =3 7450(5) nm, c =1 0917(3) nm, β =92 51(2)°, V =3 962(1) nm 3, Z =4, D c=1 639 g/cm 3, μ =1 676 mm -1 , F (000) =1936, R 1=0 0388, wR 2=0 0775. Structure analysis shows that the europium(III) ion is coordinated to six oxygen atoms of β diketonate anions and two nitrogen atoms of phenanthroline molecule. The coordination polyhedron is an approximate square antiprism.更多还原
