Low-Temperature Infrared and Raman Spectra of Co(CH3COO)2·4X2O (X = H, D)

Abstract

The infrared spectra (4000–200 cm−1) at 300 K and 95 K, and Raman spectra (4000–40 cm−1) at 300 K and 130 K of the titled compounds are reported A varying degree of deuteration has been used to assign the modes of water Analysis of the spectra confirms the known structure that has one type of acetate ion and two types of water groups in the unit cell H2O(I) retains approximately C2 v symmetry while H2O(II) is distorted to C s
