Abstract:
A new basic nickel carbonate Ni 12 (CO 3 ) 8 (OH) 8 · ( x – 1)H 2 O or Ni 12 (CO 3 ) 8 (OH) 6 O · x H 2 O ( x = 6–8) was synthesized by two hydrothermal methods. The crystal structure was determined in the cubic space group P $\bar {4}$ 3 m (215) with a = 8.3814(2) Å by laboratory high‐resolution X‐ray powder diffraction with the application of global optimization methods and Rietveld refinement. The crystal structure consists of edge‐linked [NiO 6 ] octahedra and carbonate units that form cages. The interconnected cages form channels filled with disordered water molecules. This causes a zeolite‐like behavior of the water molecules, as shown by thermogravimetric analysis coupled with infrared spectroscopy (TG–IR) and in situ X‐ray powder diffraction experiments up to 300 °C. In addition, the title compound was characterized by elemental analysis, scanning electron microscopy, and Raman and UV/Vis spectroscopy. The title compound was proven to be a pure carbonate and not nickel hydrogen carbonate (PDF 15‐0782), as was assumed before.
