Single crystals of sodium formate dihydrate, NaHCO2.2H(2)O, have been prepared from aqueous solutions of sodium formate, NaHCO2, via the trihydrate, NaHCO2.3H(2)O. They are orthorhombic, space group Cmca, with a = 7.070(4), b = 14.534(2), c = 8.706(2)Angstrom and Z = 8. The structure, including the hydrogen atoms, was refined to R = 0.054, R(w) = 0.065 for 479 unique reflections with I > 3 sigma (I). It comprises buckled layers formed by NaO6 octahedra which are edge- and corner-sharing. The octahedral coordination of the sodium ions is achieved by two oxygen atoms from two different end-on bonded formate ions and four water oxygen atoms. The O...H distances show clearly that strong hydrogen bonds are not involved in the bonding system.
