| Abstract: | Na7I2(OH)5: A Hydroxide Iodide in the System NaOH/NaI The pseudobinary system NaOH/NaI is investigated by X-ray methods. The crystal structure of the compound Na7I2(OH)5 was solved by single crystal data: Na7I2(OH)5: P4/nmm, Z = 2, a = 7.748(2) Å, c = 10.260(3) Å, Z(Fo) = 443 with (Fo)2 ≥ 3σ(Fo)2, Z(parameter) = 28, R/Rw = 0.044/0.059 Na7I2(OH)5 crystallizes in a new type of structure which contains puckered layers of ∞2[Na7(OH)52+] connected via iodide ions. |
