Using in situ X-ray diffraction, we have investigated the high-pressure behavior of β-Ni(OH)2 upto 10 GPa. No phase transformation was observed in this pressure range. Our studies show that the diffraction peaks show inherent broadening on increase of pressure. This suggests that H-lattice may be already disordered at ambient conditions and further increase in pressure may increase the lattice disorder as observed in Co(OH)2 (Phys. Rev. B 66 (2002) 134301).
