氯化镁也称为氯镁石，是一种无色结晶固体。它天然具有非常强的吸湿性。它可溶于水和酒精。它可通过在干燥的氯化氢气流中加热水合氯化镁晶体或通过加热氯化镁铵来制备。无水氯化镁可从氯化镁六水合物结晶为小叶。它具有导电性。MgCl 2 的晶体结构是层状的。该结构是由Mg 2+ 离子占据的八面体孔层交替紧密堆积而成的立体结构。 Also known as chloromagnestite, magnesium chloride is a colorless crystalline solid. It is very hygroscopic in nature. It is soluble in water and alcohol. It can be prepared by heating hydrated magnesium chloride crystals in a current of dry hydrogen chloride or by heating magnesium ammonium chloride.Anhydrous magnesium chloride crystallizes from magnesium chloride hexahydrate as leaflets. It is electrically conductive. The crystal structure of MgCl 2 is layer like. The structure is cubic close packing with alternate layers of octahedral holes occupied by Mg 2+ ions.
