标题化合物,线性多聚的三(μ-β-苯基丙烯酸)镧,被合成并得到晶体.X-衍射结构分析表明[La(β-C6H5HCOO)3]为三方晶系,R3c空间群,晶体学数据:a=13.344(1)A,α=116.13(1)°V=1182.2(4)A3,Z=2,Dx=1.63g/cm3,μ=1.85mm-1,F(000)=576.573个可观察的衍射点(Ⅰ>3σ(Ⅰ)),最终偏差因子R=0.031,Rw=0.036.在每个配位单元中,La与来自六个羧酸根的九个氧原子配位.晶体结构由沿晶胞体对角线方向无限伸展的一维聚合链组成,-La-La-重合于三重轴.
The title compound, linearly-polymerized lanthanum tris ((3-phenylacrylate), was synthesized and gave crystals. X-ray diffraction analysis shows that [La (β-C6H5HCOO) 3] is a trigonal system with R3c space group and crystallographic data: a = 13.344 (1) A and α = 116.13 (1) ° V = 1182.2 (4) A3, Z = 2, Dx = 1.63g / cm3, μ = 1.85mm-1, F (000) = 576.573 observable diffraction points (Ⅰ> 3σ (Ⅰ) Factor R = 0.031, Rw = 0.036. In each coordination unit, La coordinates with nine oxygen atoms from six carboxylates. The crystal structure consists of a one-dimensional polymeric chain extending infinitely along the diagonal of the cell body, and -La-La- coincides with the triplet axis.
