dc.description.abstract | <p>A new framework cobalt(II) hydroxyl phosphate, Co<sub>2</sub>PO<sub>4</sub>OH, was prepared by ionothermal synthesis using 1-butyl-4-methyl-pyridinium hexafluorophosphate as the ionic liquid. As the formation of Co<sub>2</sub>PO<sub>4</sub>F competes in the synthesis, the synthesis conditions have to be judiciously chosen to obtain well-crystallized, single phase Co<sub>2</sub>PO<sub>4</sub>OH. Single-crystal X-ray diffraction analyses reveal Co<sub>2</sub>PO<sub>4</sub>OH crystallizes with space group <em>I</em>4<sub>1</sub>/<em>amd</em> (<em>a</em> = <em>b</em> = 5.2713(7) Å, <em>c</em> = 12.907(3) Å, <em>V</em> = 358.63(10) Å<sup>3</sup>, and <em>Z</em> = 4). Astonishingly, it does not crystallize isotypically with Co<sub>2</sub>PO<sub>4</sub>F but rather isotypically with the hydroxyl minerals caminite Mg<sub>1.33</sub>[SO<sub>4</sub>(OH)<sub>0.66</sub>(H<sub>2</sub>O)<sub>0.33</sub>] and lipscombite Fe<sub>2–<em>y</em></sub>PO<sub>4</sub>(OH) (0 ≤ <em>y</em> ≤ 2/3). Phosphate tetrahedra groups interconnect four rod-packed face-sharing <sub>∞</sub><sup>1</sup>{CoO<sub>6/2</sub>} octahedra chains to form a three-dimensional framework structure. The compound Co<sub>2</sub>PO<sub>4</sub>OH was further characterized by powder X-ray diffraction, Fourier transform–infrared, and ultraviolet–visible spectroscopy, confirming the discussed structure. The magnetic measurement reveals that Co<sub>2</sub>PO<sub>4</sub>OH undergoes a magnetic transition and presents at low temperatures a canted antiferromagnetic spin order in the ground state.</p> | |
