CoCH3COO6

CoCH3COO6, also known as cobalt(II) acetate hexahydrate, is an inorganic compound with the chemical formula Co(CH3COO)2·6H2O. It is a coordination complex consisting of a cobalt(II) ion surrounded by two acetate ions and six water molecules. The compound is commonly used in chemical synthesis, particularly in the preparation of other cobalt complexes.

Cobalt(II) acetate hexahydrate is typically prepared by the reaction of cobalt(II) oxide or cobalt(II) carbonate with acetic acid. The resulting solution is then evaporated to yield the hydrated salt. The compound is a blue crystalline solid that is soluble in water and slightly soluble in ethanol.

In solution, CoCH3COO6 exists as a hexaaquacobalt(II) ion, [Co(H2O)6]2+, with two acetate ions coordinated to the cobalt center. The compound is often used as a precursor in the synthesis of other cobalt compounds, such as cobalt(II) acetate tetrahydrate and cobalt(II) acetate monohydrate. It is also used in analytical chemistry as a standard for cobalt determination.

CoCH3COO6 is a coordination compound, meaning that the cobalt(II) ion is coordinated to the oxygen atoms of the acetate ions and water molecules. This coordination results in a distorted octahedral geometry around the cobalt center. The compound is stable under normal conditions but may decompose upon heating, releasing water and forming cobalt(II) acetate.

The safety profile of CoCH3COO6 is generally considered low. However, like all chemical compounds, it should be handled with care, especially in a laboratory setting. Prolonged exposure to the compound may cause skin and eye irritation, and it should be kept out of reach of children.
