Solid Phase Synthesis and Characterization of Serine Complex of Bismuth(Ⅲ)

通过碘化铋与丝氨酸锂盐间的室温固-固反应合成了纳米丝氨酸铋(Ⅲ)配合物:(C3H6O3N)2Bi(μ-I)2Bi[(C3H6O3N)I].H2O.经元素分析、X-射线粉末衍射(XRD)、远红外光谱和差热-热重分析(TG-DTA)等进行表征,确定了配合物的组成和结构.同时对XRD衍射数据进行指标化,确定配合物的晶系和晶胞参数:丝氨酸铋配合物的晶体结构属于正交晶系,其晶胞参数为a=0.796 7nm,b=1.987 5nm,c=2.203 4nm.

New serine complex of bismuth（Ⅲ）,（C3H6O3N）2Bi（μ-I）2Bi[（C3H6O3N）I]·H2O was synthesized by the solid phase reaction at room temperature.The complex has been characterized by elemental analysis,X-ray powder diffraction,far-infrared spectra and TG-DTA analysis.The results of indexing of the X-ray diffraction patterns indicate the crystal structure of bismuth complex with serine belongs to a orthorhombic system and the lattice parameters are： a=0.796 7 nm,b=1.987 5 nm,c=2.203 4 nm.
