本文对配合物[Cu(DPA)μ-NO3]n.3nH2O(1)(DPA=2,2’-联吡啶胺)合成、结构和光谱性能进行了描述。(1)属于单斜晶系,P21/c空间群。中心金属离子CuII处于扭曲的四方锥的配位环境中:一个DPA上的两个N原子和一个NO3-的两个O原子位于四方锥底部平面,轴向位置由另一NO3-的O原子占据。每一个NO3-的两个氧原子与CuII鳌合,且另一氧原子与相邻的CuII配位形成一维Z型链结构。链与链之间靠分子间的相互作用力在bc面形成二维结构。此外,我们运用TG-DTG热分析技术结合红外光谱对其热分解行为和热稳定性进行了探讨,并对其热分解反应进行了非等温动力学计算,得到了相应的动力学参数。
The synthesis, structure and spectral properties of Cu (DPA) μ-NO3] n.3nH2O (1) (DPA = 2,2’-bipyridyl amine) were described in this paper. (1) belongs to the monoclinic system, P21 / c space group. The central metal ion CuII is in a distorted tetragonal pyramid coordination environment: two N atoms on one DPA and one O3- are located at the bottom of the tetragon cone, and the axial position is occupied by another O3 atom . Two oxygen atoms of each NO3- are chelated to CuII, and the other oxygen atom is coordinated with adjacent CuII to form a one-dimensional Z-type chain structure. Chain and chain by the interaction between molecules in the bc surface to form a two-dimensional structure. In addition, TG-DTG thermal analysis and infrared spectroscopy were used to investigate the thermal decomposition behavior and thermal stability. The thermal decomposition reaction was calculated by non-isothermal kinetics and the corresponding kinetic parameters were obtained.
