[n－CnH2n＋1NH3]2ZnBr4层型配合物的拉曼光谱

摘要/Abstract

摘要： 研究了标题配合物(n=7¹2,16)(简记为C_nZnX,X=Br,C1)的拉曼光谱.对主要谱带进行了归属,讨论了光谱随烷烃链长和卤索配体的变化.表明卤素配体对R-NH阳离子层离子的内振动间接产生影响.C-H伸缩、C-变角、C一C伸缩和-NH₃摇摆振动以及纵向声子模对此敏感,C_nZnBr配合物阳离子层的链间相互作用、链扩展程度和氢键强度均比C_nZnCl配合物的低.阴离子和阳离子层结构具有相关性.

Abstract: The title complexes with n=7¹2,16 have been studied by Raman spectroscopy.The assignments of the main bands have been made. The halogens in the anion layer influ-ence indirectly on the internal vibrations of R-NH₃⁺ ions in the cation layer. The C-H stretching, CH₂ bending,C-C stretching and NH₃ rocking vibrations as well as LAM aresensitive to the effect of halogens. They present obvious differences in frequency value, rela-tive intensity ratio and splitting pattern. The structure of the cation layer closely interrelates to the structure of anion layer.

Key words: bis(n-alkylammonium) tetrahalogenozincate, Raman spectroscopy, layer struc-ture
