An Amorphous Phase of Zinc and Silicon at Composition Zn 2 Si 5 (:H, OH)
An amorphous phase at composition Zn 2 Si 5 (:H,OH) was prepared by oxidation of the precursor phase Li 2 ZnSi at 80 °C in the ionic liquid of n ‐dodecyltrimethylammonium chloride (DTAC) and AlCl 3 in 1:1 molar ratio, followed by removal of elemental zinc by dilute aqueous HCl. The product was struc...
