Figure 1
Malachite-like (top) and rosasite-like (bottom) crystal structures of Co2CO3(OH)2 as obtained from DFT calculations. The rosasite-like structure is displayed with the atomic positions shifted in a way that maximizes the coincidence with the malachite structure and does not follow the values listed in Table 2. Colour shading is used to represent alternative cells with different values of the monoclinic angle. The green-shaded cell was used for the DFT calculations. Colour code: Co blue, C grey, O red and H white. |
