IR,UV AND NMR SPECTROSCOPIC STUDY OF 1,4,7,10,13,16-HEXAAZACYCLOOCTADECANE AND ITS Pd^2+, Cr^3+ COMPLEX COMPOUNDS

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.
