Neutron diffraction and Raman spectroscopy were performed to determine the structure and chemical formula of nesquehonite. The difference between our study and Hales et al. (2008) strongly indicates that nesquehonite can have two chemical formulas, Mg(OH)(HCO3)・2H2O and MgCO3・3H2O depending on the pH in the solution. That is, nesquehonite grown in a solution with pH around neutrality would have the chemical formula of Mg(OH)(HCO3)・2H2O, but that in a strongly alkaline solution results in the chemical formula of MgCO3・3H2O.
