| 摘 要： | 用X射线衍射法测定了甲酸钡的晶体结构,其晶体结构属正交晶系,空间群P_(212121),晶胞参数为a=679.1(9)pm,b=889.6(2)pm,c=764.3(2)pm,晶胞体积V为4.6172×10~8pm~3,晶胞分子数z=4,晶胞密度D_c=3.271g/cm~3,钡原子周围有8个氧原子配位组成六面体,每个氧原子分属于每个甲酸根,即每个甲酸根只提供一个氧原子与钡配位,B_a—O键键长为274.1～287.4pm,甲酸钡具有较好的光学倍频效应。

| Abstract: | The crystal structure of Barium Formate was determined byX-Ray diffraction.The structure of barium formate is an orthorhombic system.Its space group volume and molecular number per cell are presented in this paper.There are eight coordinately linked oxygen atoms around Ba atom to make up a hexagonal system The bonding distance of barium and oxygen is 274.1~287.4 pm.There exists an optical frequency-doubling effect in barium formate. |
