| Abstract: The title complex has been synthesized and its crystal and molecular structure have been determinied with a Enraf-Nonius CAD4 four cycle X-ray diffractometer. The crystal is triclinic with space group P1(No. 2). Two formula units in a cell of dimensions a =12.880(4), 6 =13.649(7), c =21.670(5)Å, a=93.14(3), β=91.63(2)°, γ=115.99(4)°. A total number of 7132 independent diffraction data were collected, of which 4925 observable reflections (I > 3σ) were used for structure refinement to a final deviation factor R of 0.089, and a weighted Rw of 0.091.The neodymium atom is coordinated to eight oxygen atoms. Six of them are from three bidentate ligand PMTFP. The rest are from two Ph3PO. The average bond length of eight Nd-O bonds is 2.410Å. The coordination polyhedron take a distorted square antiprism arrangement. |
