| Abstract: The preparation, crystal structure and infrared spectra of europium tris(1, 3-diphenyl-4-acetyl-pyrazolone-5)·(o-phenanthroline)or Eu(DPAP)3(o-phen)were presented. The crystal structure has been determined by X-ray analysis from intensity data for 4900 independent reflections. The crystal is monoclinic, space group C2h6-C2/c, with eight molecules per unit cell. The cell dimensions are; a=23.021(15)Å, b=22.988(11)Å, c=23.549(9)Å, β=109.27(4)° and other parameters are, F(000)=4527.00, μ=11.28cm-1(Mo Ka).The coordination number of europium is eight. Each europium atom is coordinated by six oxygen atoms and two nitrogen atoms arranged at the vertices of a distorted archimedean square antiprism. |
