摘　　要：以合成的新型配合物Ni2（NO3）4（APTY）4晶体结构表征结果为基础，运用晶体化学和纳米科技的基本原理，对Ni2（NO3）4（APTY）4的纳米化进行了研究。通过对该配合物不同纳米尺度微粒的晶胞数、原子数、表面原子数及其比例的计算，分析讨论了微粒纳米尺度变化与结构稳定性、化学活性的相关关系，预测了该微粒的最小及最佳纳米尺度。To detect the specific characteristics of the novel polybasic coordination in the title, which has been synthesized, herein, on the basis of the characterization of the crystal structure, the minimum dimension of nano-Ni2（NO3）4 （APTY）4 has been assumed by means of crystal chemistry fundamentals and nanometer science and technology. And then some theoretical foundation has also been given to the assumption through the calculation of the crystal cell numbers, the atomicity, the surface layer atomicity and its proportion. In addition, this paper has also analysed and discussed the coherent relationships between the structural stability and the chemical activity as the dimension of the title compound particles varied. The optimum dimension of its nano-particle is theroretically divined to be about 230nm.
