The structure of the reaction product of boric acid, chloral hydrate, and potassium carbonate in H2O, potassium bis(carbonato)borate hydrate K[B(CO2-μ-O-CO2)2]·2H2O, was determined by X-ray crystallography. The compound crystallized in the orthorhombic system, and was characterized to be in the space group Aba2, with cell parameters of a = 11.0579(10)Å, b = 11.1695(10)Å, c = 9.0504(9)Å, Z = 4, and V = 1117.83(18)Å3. In the crystal structure, intermolecular O–H···O hydrogen bonds link the molecules into a supramolecular structure, in which they may be effective in stabilizing the structure. The B atom espouses a distorted tetrahedral geometry with four O atoms of carbonate ligands.
