A new hydrate of magnesium carbonate, MgCO(3)·6H(2)O

During investigations of the formation of hydrated magnesium carbonates, a sample of the previously unknown magnesium carbonate hexa­hydrate (MgCO(3)·6H(2)O) was synthesized in an aqueous solution at 273.15 K. The crystal structure consists of edge-linked isolated pairs of Mg(CO(3))(H(2)O)(4) octa­h...

Sumario:During investigations of the formation of hydrated magnesium carbonates, a sample of the previously unknown magnesium carbonate hexa­hydrate (MgCO(3)·6H(2)O) was synthesized in an aqueous solution at 273.15 K. The crystal structure consists of edge-linked isolated pairs of Mg(CO(3))(H(2)O)(4) octa­hedra and noncoordinating water mol­ecules, and exhibits similarities to NiCO(3)·5.5H(2)O (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(3)·3H(2)O) at room temperature.
