Ag₂Na

Ag₂Na是一种二元金属间化合物，由银和钠组成。

制备及性质[编辑]

Ag₂Na可以由银和钠的单质在750 °C反应，并在322 °C以下由包晶反应析出：^[2]

{\mathsf {2Ag+Na\ {\xrightarrow {322^{o}C}}\ Ag_{2}Na}}

它可以和水反应，生成纳米银、氢氧化钠并放出氢气：^[3]

{\mathsf {2Ag_{2}Na+2H_{2}O\ {\xrightarrow {\ }}2NaOH+4Ag+H_{2}\uparrow }}

它也能和乙醇反应。^[2]

Ag₂Na属于立方晶系，空间群F d3m，晶胞参数a=0.792，Z=8，具有MgCu₂结构。 ^[4]^[5]^[6]
