A novel cobalt sodium phosphate hydroxide with the ellenbergerite topology: crystal structure and physical properties.

The novel phase Na2-xCo6(OH)3[HPO4][Hx/3PO4]3 (x≈ 1.1) was prepared by hydrothermal synthesis at 553 K. Its crystal structure was determined using single-crystal X-ray diffraction data and refined against F(2) to R = 0.052, including positions of all hydrogen atoms. The compound crystallizes in the hexagonal space group P63mc, with unit-cell parameters a… CONTINUE READING
