碱式邻苯二甲酸氢镧的制备及结构分析
Preparation and Structural Characterization of Lanthanum Hydroxide Hydrogen Diphthalate Monohydrate
【摘要】 采用水膜反应法合成了一水合碱式邻苯二甲酸氢镧,电子衍射和X射线粉末衍射谱图表明其晶体结构属单斜晶系,空间群Plal(No.7),晶胞参数:a=2.0587nm,b=0.6235nm,c=1.3113nm,β=94.64°,Z=4.用傅里叶变换红外光谱仪测定了红外吸收光谱,并对各吸收带进行了归属,讨论了羧酸根与金属离子的配位结构。
【Abstract】 The LaOH(C8H5O4)2·H2O was prepared by employing water film reaction method. The electron and X-ray diffraction patterns show that the complex belongs to a monoclinic system, Plal, Z=4, α=2. 0587 nm, b=0. 6235 nm, c=1. 3113 nm, β=94. 64°. The IR spectrum was recorded with a FT- IR spectrometer, and the vibrational bands were assigned by comparison with that of calcium phthalate monohydrate. The coordinate structure of carboxylate groups with lanthanum ions was discussed.
