Low-Temperature Infrared and Raman Spectra of Co(CH 3 COO) 2 ·4X 2 O (X = H,D)

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 C₂v symmetry while H₂O(II) is distorted to C _s
