合成了2个锌配合物[Zn(mtyaa)2(H_2O)4]·4H_2O(1)和[Zn(bpe)(mtyaa)2(H_2O)2]n(2)(Hmtyaa=2-(5-甲基-1,3,4-噻二唑)-硫乙酸;bpe=1,2-双(4-吡啶基)乙烷),用X射线单晶衍射仪测定了配合物的单晶结构,并对它进行了元素分析、红外光谱、热重和粉末X射线衍射等表征。配合物1和2的晶体分别属于三斜晶系和单斜晶系,空间群分别为P1和C2/c。π-π相互作用以及配位水和游离水分子与羧基氧之间的氢键作用将配合物1的单分子结构连成三维网状结构。配合物2中配位水与羧基氧以及配体中的氮原子之间的氢键作用将相邻链连接成二维平面结构。
Two Zn (mtyaa) 2 (H_2O) 4] · 4H_2O (1) and [Zn (bpe) (mtyaa) 2 (H_2O) 2] n Methyl-1,3,4-thiadiazole) -thioacetic acid; bpe = 1,2-bis (4-pyridyl) ethane). The single crystal structure of the complex was determined by X-ray single crystal diffractometry. It was also characterized by elemental analysis, infrared spectroscopy, thermogravimetry and powder X-ray diffraction. The complexes 1 and 2 belong to the triclinic and monoclinic systems, respectively, and the space groups P1 and C2 / c, respectively. π-π interaction and the coordination between water and free water molecules and the hydrogen bond between the carboxyl oxygen complex structure 1 single molecular structure into three-dimensional network structure. In complex 2, the adjacent chains are connected into two-dimensional planar structures by hydrogen bonding between coordination water and carboxyl oxygen as well as nitrogen atoms in the ligands.
