摘要
作者对1,4,7,10,13,16-六氮杂环十八烷([18]aneN6)及其Pd2+、Cr3+ 配位化合物[Pd2([18]aneN6)Br2]Br2· 4H2O、[Cr([18]aneN6)]Br3进行了红外、紫外 和核磁共振光谱学研究。红外图谱中与Pd2+、Cr3+配位化合物Pd-N、Cr-N配位键伸 缩振动相对应的谱峰位置分别为 502 cm-1和 492cm-1。认为 Pd2+配位化合物水溶液 在 354 nm(ε=1414)处和Cr3+配位化合物水溶液在 467. 2 nm(ε=220)、366. 2nm(ε =80)处的紫外吸收为中心离子Pd2+、Cr3+的电子d轨道d-d能级跃迁所致。
Instrument Center,Gifu Pharmaceutical University,,Japan This paper reports the IR, UV and NMR spectroscopic study of 1, 4, 7, 10, 13, 16- hexaazacyclooctadecane and its Pd2+,Cr3+ complex compounds. In this study, the IR peaks corresponding to the stretching vibration of Pd-N,Cr-N complex bonds were determined to be at 502 cm-1 and 492 cm-1 respectively; the UV absorption peak at 354 nm(ε=1414) of water solution of the Pd2+ complex compound and the UV absorption peaks at 467. 2 nm(ε=220), 366. 2 nm(ε=80) of water solution of the Cr3+ complex compound were supposed to have been resulted from the d- d energy transition of electron d orbits of Pd2+ and Cr3+ central ions.
