氟化锰是一种无机化合物,化学式为MnF2。它是一种淡粉红色固体,其颜色源自于二价锰离子的特征色。它可用于特种玻璃和激光器的制造。[3]
制备与结构
- MnCO3 + 2 HF → MnF2 + CO2↑ + H2O
也可由氯化锰和过量的氟化铵反应,得到NH4MnF3,它在二氧化碳中加热至290~300 °C得到氟化锰。[5]它也能通过四氧化三锰(或草酸锰)与氟化铵加热反应制得。[6]
氟化锰存在多种晶相,P42/mnm(金红石型)和P42m是已知的,[7]金红石型的氟化锰在高压会转变为α-PbO2相。[8]
反应
氟化锰和M2MnF6(M=K, Rb, Cs)在真空中加热(或氮气环境下加压,M=NH4)反应,可以得到相应的MMnF4。[9]它可以被氟气氧化至四氟化锰;[10]而在氟化氢中的反应会生成三氟化锰,氟化氢中生成四氟化锰还需紫外光的照射。[11]它和三氟化锰反应,还能得到Mn2F5和Mn3F8。[12]氟化锰和过量二氟化氙加热反应,可以得到XeF2·MnF4,反应中Mn2+被氧化至Mn4+;[13]KrF2·MnF4则需在低温氟化氢中由氟化锰和二氟化氪反应得到,室温时,它会分解为四氟化锰、二氟化氪、氪和氟气。[14]
它在潮湿的氮气中加热至500 °C发生水解,生成一氧化锰,[15]在潮湿空气中加热除了水解外还会发生氧化反应;它和硫蒸气的反应发生在氟化锰的表面。[16]
