2. Cobalt(II) acetate tetrahydrate is used as an industrial catalyst to harden paints and varnishes, an active catalyst for oxidation and esterification reactions. It is also used to prepare metal complexes having unusual coordination geometry.
3. Cobalt(II) acetate tetrahydrate may be used in the preparation of [Co3(OH)2(H2O)2(aptet)4] (aptet = 4-aminophenyltetrazolate) and new tetradentate cobalt(II)-Schiff base complex.
Application
Cobalt(II) acetate tetrahydrate may be used in the synthesis of the following:
cobalt nanoparticles.
cobalt(II)–aminophenyltetrazolate coordination polymer.
tricobalt complexes with mixed μ-acetato and μ-pyrazolato ligands.
General Description
Cobalt(II) acetate tetrahydrate has an octahedral structure, the central cobalt orbit is coordinated by four water molecules and two acetate ligands. Cobalt(II) acetate tetrahydrate becomes anhydrous by 140oC.
Safety Profile
Moderately toxic by
ingestion. Questionable carcinogen. A skin
and eye irritant. Human mutation data
reported. See also COBUT
COMPOUNDS. When heated to
decomposition it emits acrid smoke and
irritating fumes.
Purification Methods
Several recrystallisations from 50% aqueous acetic acid give the tetrahydrate. It is converted to the anhydrous salt by drying at 80o/1mm for 60hours. [Beilstein 2 IV 120.]
Check Digit Verification of cas no
The CAS Registry Mumber 6147-53-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,4 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6147-53:
(6*6)+(5*1)+(4*4)+(3*7)+(2*5)+(1*3)=91
91 % 10 = 1
So 6147-53-1 is a valid CAS Registry Number.

Reaction of octacarbonyldicobalt with the free radicals galvinoxyl and 2,2-diphenyl-1-picrylhydrazyl. Attempts to scavenge the tetracarbonylcobalt radical

The addition of galvinoxyl or 2,2-diphenyl-1-picrylhydrazyl to octacarbonyldicobalt in n-octane solution results in the loss of all carbon monoxide ligands and the formation of Co(II)-containing products.
Thermal analysis of cobalt(II) salts with Some carboxylic acids
Ingier-Stocka,Grabowska
, p. 115 - 123 (2008/10/08)
The thermal analysis of CoC2O4·2H2O, Co(HCOO)2·2H2O and Co(CH3COO)2·H2O was carried out with simultaneous TG-DTG-DTA measurements under non-isothermal conditions in air and argon atmospheres. The intermediates and the end products of decomposition were characterised by X-ray diffraction and IR and UV-VIS spectroscopy. The decomposition of the studied compounds occur in several stages. The first stage of dissociation of each compound is dehydration both in air and argon. The next stages differ in air and argon. The final product of the decomposition of each compound in air is Co3O4. In argon it is a mixture of Co and CoO for cobalt(II) oxalate and cobalt(II) formate but CoO for cobalt(II) acetate.
