    Unprecedented Formation of Potassium Borate Based Carbonate from Chloral Hydrate, Potassium Carbonate and Boric Acid
    (Japan Soc Analytical Chemistry, 2021) Tombul, Mustafa; Turkmenoglu, Elmas; Shin, Onur
    The structure of the reaction product of boric acid, chloral hydrate, and potassium carbonate in H2O, potassium bis(carbonato)borate hydrate K[B(CO2-mu-O-CO2)(2)]center dot 2H(2)O, 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)angstrom, b = 11.1695(10)A, c = 9.0504(9)angstrom, Z = 4, and V = 1117.83(18)angstrom(3). In the crystal structure, intermolecular O-H center dot center dot center dot 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.
