O,O′-二正丁基二硫代磷酸锌碱式双盐的晶体结构

The Crystal Structure of Basic Zincic Double Salts of O,O′-di-n-butyl Hydrogen Phosphordithioates

用 X—光单晶衍射方法测定了一个由氧桥连结的二正丁基二硫代磷酸锌碱式双盐的晶体结构.晶体属三斜晶系,空间群为 Ci—(?);晶胞参数:a=12.522(2)°A,b=14.514(2)°A,c=14.528(2)(?).α=112.13(1)°,β=106.72(1)°,Υ=106.65(1)°.本文用直接法和付里叶综合法解出结构.最终的一致性因子 R=0.086.结构分析表明,分子中存在一个由处于对称中心的氧和与其四配位的锌所构成的骨架,金属锌呈空缺无序状态.

The crystal structure of Basic Zincic Double Salts of O,O′-di-n-butylHydrogen Phosphordithioates is determined by means of X-ray.Thecrystal is triclinic,space group P(1)with a=12.522(2)(?),b=14.514(2)(?),c=14.528(2)(?),α=112.13(1)°,β=106.72(1)°,and γ=106.65(1)°.Thecrystal structure is carried out by Direct Method and Fourier Synthesis.The final R value is 0.086.The structure analysis shows that there existsa framework consisting of only one oxygen atom situated at the center ofthe cell and connected quadrangularly with four zinc atoms.The zine atomsare obviously in disorder distribution with absence.
