Table 3.
X-ray diffraction parameters of α-Ni(OH)2 calculated using the unit cell shown in figure 4 and the lattice parameters reported by Pandya et al. [32]. Fewer significant digits are provided for peaks involving the crystallographic c-axis [(001), (111), etc.]. Diffraction angles are listed for Cu Kα (λ=1.542 Å) and Co Kα (λ=1.789 Å) X-ray sources.
| Miller indices (hkl) | d (Å) | 2θCuKα(°) | 2θCoKα(°) |
|---|---|---|---|
| (001)a | 8.0 | 11.1 | 12.8 |
| (100) | 4.62 | 19.2 | 22.3 |
| (002) | 4.0 | 22.2 | 25.8 |
| (110) | 2.67 | 33.6 | 39.2 |
| (111) | 2.5 | 35.5 | 41.4 |
| (200) | 2.31 | 39.0 | 45.6 |
| (004) | 2.0 | 45.3 | 53.1 |
| (210) | 1.75 | 52.4 | 61.6 |
| (301) | 1.5 | 61.3 | 72.5 |
aWe have used the unit cell definition and Miller indices reported by Bode et al. and McEwen, in which the intersheet distance, dIS=c[4,28]. However, some authors use a different unit cell definition, such that dIS=c/3 (e.g. [33,34]). In these sources, the Miller indices also vary by a factor of three (e.g. where we report (001), they would report (003), etc.).
