中文摘要 | 采用溶液析出法,合成了以2-(2′-羟基-5′-甲基苯基)苯并三唑(HMPB)为配体的多氮杂环金属配合物M(HMPB)2(M=Co,Ni),利用元素分析、激光解析飞行时间质谱等进行了表征,并研究了新配合物的红外特征光谱和紫外-可见电子吸收光谱。结果表明:HMPB配体通过N和O原子与中心金属以二齿形式配位,中心金属的配位数为4;配合物红外特征吸收谱带位于400~2 500 cm^-1,形成金属配合物后,2-(2′-羟基-5′-甲基苯基)苯并三唑的羟基的伸缩振动吸收、CN振动峰和C─O特征吸收有明显改变,同时确定了配位键M─N和M─O的特征峰位置;配合物在紫外区有强吸收,其最大吸收峰位于335~345 nm。; Novel multi-nitrogen heterocyclic metal complexes M(HMPB)(2)(M= Co, Ni) using 2-(2'-hydroxy-5'-methyl phenyl) benzotriazole (HMPB) as ligand, were synthesized by the methanol aqueous solution precipitation method for the first time. The as-prepared samples were characterized by element analysis and laser-desorption ionization time-of-flight mass spectrometry (LDI-TOF-MS). The Fourier transform infrared characteristic spectra (FTIR) and ultraviolet visible electronic absorption spectrum (UV-Vis) of the new complexes were also studied especially. The results show that the HMPB ligand coordinates with the center metal ions by. nitrogen and oxygen atoms in the form of bidentate ligand, and the coordination number of the center metal ions is four in the complexes; FTIR characteristic absorption band of the complexes is located in the region of 400-2 500 cm(-1). After the complexes formation, the stretching vibration of the hydroxy group of 2-(2'-hydroxy-5'-methyl phenyl) benzotriazole, the vibration peak of C=N bond and the characteristic absorption of C-O bond showed distinct changes. The IR characteristic absorption peak positions of M-N and M-O bond were also confirmed. These complexes exhibited a strong absorption in the ultraviolet region and the maximum absorption peak located in the range of 335-345 nm. |
