室温条件下合成了1个结构新颖的一维链状配位聚合物[Cd(BBTH)(SCN)_2]_n(BBTH=1,6–双(苯并三氮唑)己烷),通过元素分析、红外光谱、X-射线粉末衍射和热分析方法对其结构和性质进行了表征和研究,利用X-射线单晶衍射测定了[Cd(BBTH)(SCN)_2]_n的晶体结构,采用菌落直径法研究了配体和配合物对腐皮镰刀真菌的抑菌性。X-射线单晶衍射结果表明,晶体属于单斜晶系,空间群为P2(1)/c,配体BBTH以μ_2–桥联模式连接无机链构成一维有机无机链,相邻的一维有机无机链通过弱的π-π作用堆积为二维的层状结构,然后该π-π相互作用使二维层进一步堆积成三维超分子结构。配体和配合物对腐皮镰刀真菌的生长都具有一定的抑制作用,且配合物对腐皮镰刀真菌的抑制作用较配体BBTH更强。
One novel one-dimensional chain coordination polymer [Cd (BBTH) (SCN) _2] _n (BBTH = 1,6-bis (benzotriazole) hexane) was synthesized at room temperature. The crystal structure of [Cd (BBTH) (SCN) _2] _n was determined by X-ray single crystal diffraction. The structure of the crystal was characterized by X-ray powder diffraction and thermal analysis. The colony diameter method was used to study the antibacterial activity of the ligands and complexes on the parasitic fungi. The results of X-ray single crystal diffraction show that the crystal belongs to the monoclinic system and the space group is P2 (1) / c. The ligand BBTH forms a one-dimensional organic-inorganic chain by connecting the inorganic chain with μ_2-bridging mode. The organic-inorganic chains are stacked into a two-dimensional layered structure by a weak π-π interaction, and then the π-π interaction causes the two-dimensional layer to be further stacked into a three-dimensional supramolecular structure. Ligands and complexes have some inhibitory effects on the growth of Fusarium oxysporum fungi, and the inhibitory effect of the complexes on Fusarium oxysporum fungi is stronger than that of the ligand BBTH.
