dc.description.abstract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.
dc.description.abstractThe title compound, linear-poly [μ-β-phenylacrylato-O,O':O' ) Lanthanum ], has been synthesized and determined by X-ray single-crystal diFFraction.[La (β-C6H5CHCHCOO)3] crystallizes in the trigonal, space group R3c.Cell parameters are a= 13.344 (1 ) A,a= 116.13 (1 )°,V= 1182.2 (4) A 3,Z= 2,Dx= 1.63 g/cm3, μ= 1.85mm-1,F(000) = 576.The structure was reFined to an R of 0.031 and Rw of 0.036 For 573 observed renections.Each La atom is coordinated with nine O atoms From six carboxylato groups.The crystal structure consists of one-dimensional polymeric chains with La atoms lying on thethree-Fold axis of chains at a La-La distance of 3.991 (1) A .
