During investigations of the formation of hydrated magnesium carbonates, a sample of the previously unknown magnesium carbonate hexahydrate (MgCO·6HO) was synthesized in an aqueous solution at 273.15 K. The crystal structure consists of edge-linked isolated pairs of Mg(CO)(HO) octahedra and noncoordinating water molecules, and exhibits similarities to NiCO·5.5HO (hellyerite). The recorded X-ray diffraction pattern and the Raman spectra confirmed the formation of a new phase and its transformation to magnesium carbonate trihydrate (MgCO·3HO) at room temperature.
在对水合碳酸镁形成过程的研究中，一种先前未知的六水合碳酸镁（MgCO₃·6H₂O）样品于273.15 K的水溶液中合成。其晶体结构由边缘相连的孤立Mg(CO₃)(H₂O)₆八面体对和非配位水分子组成，与NiCO₃·5.5H₂O（黑菱镍矿）具有相似性。记录的X射线衍射图谱和拉曼光谱证实了新相的形成及其在室温下向三水合碳酸镁（MgCO₃·3H₂O）的转变。
