【Abstract】 This article reports the molecular structure of quinolincte-trakis （4, 4, 4-trifluoro-1-（2-thienyl）-1, 3-butanedione） Lanthanum （Ⅲ）. The molecular formula is LaC₄₁H₂₄O₈S₄F₁₂N. The erystal is trielinic with space group P1 , α=19.752（A） b=12.361（A）, c=10.988（A）, α=98.08°, β=98.95°,γ=99.61°, and z=2. The intensity data were collected on a PW-1100 four circle diffractometer. The lotal number of independent reflections amounts to 8064 The crystal slructure has been detcrmined by heavy atom method and refined by bloek least square refinemeni for posilional parameters and anisotropie temperature faetors of nonhydrogen atoms. The final R factor is 0.0730 for 5346 reflexions. （AH the positions of hydrogen were located by tile difference syntheses.）更多还原
