Kamotoïte-(Y), a new uranyl and rare earth carbonate, has been studied by thermal treatment. The mineral has also been characterized by IR spectroscopy and the presence of the bidentate binding of carbonate to uranyl ion has been confirmed. Likewise, the U-O bond lenght in the uranyl group can be estimated by IR measurements.

AbstractMagnesium acesulfamate, Mg(C4H4NO4S)2·6H2O, was prepared by the reaction of acesulfamic acid and magnesium carbonate in aqueous solution, and characterized by elemental analysis. Its crystal structure was determined by single crystal X-ray diffraction methods. The substance crystallizes in the triclinic space group P1̅ with one molecule per unit cell. The FTIR spectrum of the compound was also recorded and is briefly discussed. Some comparisons with other simple acesulfamate and saccharinate salts are also made.
