Magnetic propertiesSpectroscopyThermal analysisGreen singleヽrystals of the hydroxochromate(III) CaNa[Cr(OH)6] were grown under highly alkaline hydrothermal conditions at about 200 °C. The starting materials Ca(NO3)2·6H2O and Cr(NO3)3·9H2O were reacted in a mixture of water and sodium ...
The redox reaction between D-galactonic acid and potassium chromate yields {((lyxonateH(-1)) (galactonateH(-1)) Cr(OH2))K . H2O}(n), with both aldonate molecules acting as bidentate ligands with the carboxylate and one alkoxo function as the donor sites. The shift of the CO2-...
