摘要
研究了［ｎ－ＣｎＨ２ｎ＋１ＮＨ３］２ＭＸ４（Ｍ＝Ｃｕ、Ｍｎ、Ｃｄ、Ｚｎ、Ｃｏ…；Ｘ＝Ｃｌ，Ｂｒ；ｎ＝７—１２，１６）系列标题配合物的光谱性质．给出了特征谱带的经验归属．讨论了烷烃链链长、中心金属离子和卤素配体对配合物阳离子层的堆积结构、分子间相互作用和分子构象以及氢键强度等方面的影响．结果表明，Ｍ＝Ｃｕ、Ｍｎ、Ｃｄ和Ｍ＝Ｚｎ、Ｃｏ的两组配合物光谱特征明显不同．发现Ｃ－Ｈ伸缩、ＮＨ３变角、Ｃ－Ｃ伸缩振动、某些ＣＨ２平面摇摆和非平面摇摆振动对金属离子敏感．
Abstract Infrared spectra of the title compounds [n--C.Hu+,NH312MX.(M = Cu, Mn, Cd, Zn, Co;'X= CI, Br; n = 7--12, 16) (abr. C.MX) in the room temperature phase have been studied. Thecxpericncc assignments of the main bands have been made.The effecting of the chain length,center mctul ions and halogcns on the packing structure in the canon layers,interaction of alkylChains and the molecular conformation as well as the strength of the hydrogen bonds were discussed. The results show that the C--H stretching, CHZ bending, NH3 deformation, C-Cstretching and some CHZ wagging as well as CH, rocking vibrations are sensitive to the chainlength, center metal ions and halogcns.
