Title: Cobaltous Carbonate
CAS Registry Number: 513-79-1
Molecular Formula: CCoO3
Molecular Weight: 118.94
Percent Composition: C 10.10%, Co 49.55%, O 40.35%
Line Formula: CoCO3
Literature References: Occurs in nature as the mineral cobalt spar or sphaerocobaltite. Prepd by heating a soln of a cobaltous salt with Na2CO3: Schlessinger, Inorg. Synth. 6, 189 (1963) where it is the starting material for the prepn of trinitrotriamminecobalt. Review: de Bie, Doyen, Cobalt 15, 3-13; 16, 3-15 (1962).
Properties: Red powder or rhombohedral crystals. d 4.13. Almost insol in water, alcohol, methyl acetate. Does not react with cold concd HNO3 or HCl; when heated, dissolves with evolution of CO2. Oxidized by air or weak oxidizing agents to cobaltic carbonate.
Density: d 4.13
 
Derivative Type: Hexahydrate
Properties: Pink to violet-red cryst needles. Pptd when excess CO2 is present during prepn. On heating becomes anhydr by 140°. Stable in air.
 
Derivative Type: Cobaltous carbonate basic
Synonyms: Cobalt carbonate hydroxide
Molecular Formula: C2H6Co5O12
