A high‐pressure/high‐temperature experiment at 5 GPa/973 K revealed the existence of a new nickel borate hydrate. The crystal structure of Ni 3 B 18 O 28 (OH) 4 · H 2 O was elucidated through X‐ray single‐crystal diffraction. The compound crystallizes in the hexagonal space group P 6 2 m (no. 189) with the lattice parameters a = 8.2599(4) Å, c = 7.6963(4) Å, and V = 454.74(5) Å 3 . X‐ray powder diffraction, IR and Raman spectroscopy, thermogravimetric analysis (TGA), and magnetic measurements were used to characterize Ni 3 B 18 O 28 (OH) 4 · H 2 O. The effective magnetic moment and the Weiss constant were calculated to be µ eff = 3.20(1) µ B and θ P = –5.3(1) K, respectively.
