Morphology and X-ray diffraction pattern of dihydrates of cobalt (II) oxalate

Abstract

Depending on the mode of preparation three different dihydrates of cobalt (II) oxalate exist, which can be distinguished by means of X-ray diffractometry (XRD). There is a good correlation between the morphology of the crystallites and the peak heights of the maxima in the XRD-pattern. The morphology of the crystallites is determined by the precipitation procedure rather than by the crystallographic structure. The structure of the β-dihydrate has not been elucidated as detailed as stated in the literature.
