Raman spectroscopic study of chain complexes of bis(hydrazine) zine and manganese halides

The Raman spectra of polycrystalline Zn (N 2 H 4 ) 2 X 2 (X Cl or Br) and Mn(N 2 H 4 ) 2 Cl 2 were run over the range 90–3590 cm −1 . The bands observed in the higher frequency region (400–3590 cm −1 ) were assigned to perturbed hydrazine vibrations and generally agree well with previously reported infrared studies. A normal coordinate analysis was performed on the core of the complexes, metal · N 4 X 2 , and used to assign the observed metalnitrogen and metal–halide bands in the lower frequency range (90–400 cm −1 ).
