A new addictive compound, (C 2H 5) 4N +HCO - 3·H 2O, is prepared and characterized by X ray crystallography. Crystal data: space group P 2 1/ n,a =0.818 6(1) nm, b =1.533 0(3) nm, c =0.956 2(3) nm, β =97.82(2)°, Z =4, V =1.188 8(5) nm 3 , M r=209.28, ρ c=1 169 g·cm -3 , μ (MοK α)=0.090 mm -1 , F (000)=464, and R =0.048 6 for 1 837 independent reflections. In the crystal structure of the title compound, each asymmetry unit contains one bicarbonate anion, one tetraethylammonium cation and one water molecule. Bicarbonate anions and water molecules interacting with each other through hydrogen bonds constitute a zigzag composite ribbon and are arranged in un closed channels generated from the tetraethylammonium cations.
