Single-crystal vibrational spectra of some chlorine-bridged anionic chains

Abstract

Single-crystal Raman spectra are reported and assigned for (NMe₄)CdCl₃, NH₄CdCl₃, (NH₃Me)MnCl₃, CsCuCl₃, CsMnCl₃,2H₂O, and CsMnCl₃,2D₂O. Polarised far-i.r. studies have been made for (NMe₄)CdCl₃. Cscucl₃, CsMnCl₃,2H₂O, and CsMnCl₃,2D₂O. With the exception of NH₄CdCl₃, which has a complicated double-chain structure, the results are discussed in terms of factor group analysis. Line group analysis suffices for NH₄CdCl₃.
