| 摘要: 本工作合成了五个钍(Ⅳ)与β—二酮、三苯基氧化膦的三元配合物。其化学式分别为Th(TPPO)2(L)(NO3)3(L=dbm,bzac,bfac,TTA)和Th(TPPO)2(tfac)2(NO3)2,以及一个中间配合物Th(TPPO)2(NO)4,通过电导、热谱、紫外以及红外光谱的测试,对它们的性质进行了研究。化合物Th(TPPO)2(dbm)(NO3)为淡黄色晶体。晶体结构测定表明,它属正交晶系;P212121空间群;晶胞参数为a=15.5920(39)Å,b=17.4189(62)Å,c=17.9819(47)Å;z=4。3916个大于3σ(Ⅰ)的反射点参加最小二乘修正,最终偏离因子R=0.027。该配合物中,中心离子Th4+的周围有十个氧原子与之配位,三个硝酸根和三苯基甲酰甲烷均系双基配位。十个配位氧原子所构成的配位多面体是不规则多面体。 |

| Abstract: Five ternary complexes of Th(Ⅳ) with some β-diketones and tri-phenylphosphine oxide have been prepared. They have formulae of Th (TPPO)2(L)(NO3)3(TPPO=triphenylPhosphine oxide, L: dbm=diben-zoylmethane, bzca= benzoylacetone, bfac= benzoyltrifluoroacetone, TTA = thenoyltrifluoroacetone) and Th(TPPO)2(tfac)2(NO3)2(tfac= trifluoroace-tylacetone). The UV and IR spectra of the complexes have been recorded, its properties have also been studied with conductometry and thermal analysis.The crystal structure of Th(TPPO)2(dbm) (NO3)3 was determined by three dimensional X-ray data. The orthorhombic crystal has a space group P212121, a=15.5920(39)Å, b=17.4189(62)1, c= 17.9819(47)Å, V= 4883.80Å3, Z=4. The structure was solved by direct methods using Fourier syntheses, and refined by block-diagonal and full matrices least squares techniques to a final R of 0.027 for 3916 independent reflections. |
