Na7I2(OH)5: A Hydroxide Iodide in the System NaOH/NaIThe 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 = 0.044/0.059Na7I2(OH)5 crystallizes in a new type of structure which contains puckered layers of ∞2[Na7(OH)52+] connected via iodide ions.
Notes:
Das pseudobinäre System NaOH/NaI wurde röntgenographisch untersucht und die Struktur einer Verbindung, Na7I2(OH)5, mittels Röntgenstrukturanalyse an Einkristallen aufgeklärt:Na7I2(OH)5: P4/nmm, Z = 2, a = 7,748(2) Å, c = 10,260(3) Å, Z(Fo) = 443 mit (Fo)2 ≥ 3σ(Fo)2, Z(Parameter) = 28, R/Rw = 0,044/0,059.Die Verbindung kristallisiert in einem eigenen Strukturtyp, der gewellte Schichten von ∞2[Na7(OH)52+] enthält, die über I- verknüpft sind.
