| Abstract: A mixed ligand neodymium complex, [Nd(ClO4)24ph3PO]ClO4·C2H5OH, has been synthesized, and its crystal and molecular structure have been determined by single crystal X-ray diffraction technique with a four circle diffractometer. The crystal is triclinic with space group P 1. The unit cell parameters are as follpws:a= 13.475(61) A α=85.44(7)°b=15.003(15)Å β= 78.49(24) °c= 18.697(15)Å γ= 83.13(26)°Z=2 V= 3671.21Å3 dcale = 1.445g/cm3 F(000) = 1578e This complex contains ninety-nine nonhydrogeu atoms and consists of three parts:(1)a cation complex [Nd(ClO4)2·4ph3PO]+, (2) a ClO4- anion and (3) a solvent molecule, C2H5OH. The neodymium atom is coordinated to eight oxygen atoms, of which four from two bidentate ClO4- and the other four from the four ph3PO ligands. The eight coordinated oxygen atoms take a distorted delta dodecahedron arrangement around the central neodymium atom. |
