Synthesis of Low-Symmetric α-Cobalt(II) Hydroxide-Incorporated Cyanuric Acid Layers with High Néel Temperature and Large Coercivity: Structure and Magnetism

α-Cobalt(II) (Co ) hydroxide (compound ) incorporating cyanuric acid layers was synthesized via the solvothermal method. exhibited two distinct characteristics, which were different from reported α-Co hydroxides. (i) The presence of abundant consecutive hydrogen bonds between the adjacent hydroxide layers enhanced the driving force of crystallization along the direction of the axis. Thus, revealed high crystallinity without the disorder phenomenon. (ii) showed low symmetry. The configuration of Co sites did not follow the regular triangular net. The low symmetry favored the magnetic anisotropy. Thus, revealed ferrimagnetic behavior with a high Néel temperature ( = 56.8 K) and coercivity ( = 36 kOe at 2 K). The ferrimagnetic behavior of was validated via the Hubbard correction density functional theory.
