詳細

詳細

Cobalt(II) acetate tetrahydrate, commonly used as bleach and drying agent, can be produced by reacting cobalt (II) carbonate and acetic acid.[1] It undergoes decomposition on heating up to 500°C under non-isothermal conditions.[2] Its crystals exhibit monoclinic crystal system having space group P2₁/c.[3] Cobalt(II) acetate tetrahydrate undergoes hydrothermal reaction with 1,3,5-benzenetricarboxylic acid (BTCH₃) to afford Co₃(BTC)₂.12H₂O.[4]

アプリケーション

Cobalt(II) acetate tetrahydrate may be used as a cobalt source in the synthesis of cobalt nanoparticles[5] and cobalt oxide thin films. It may also be used to prepare cobalt(II)-aminophenyltetrazolate coordination polymer[6] and tricobalt complexes with mixed μ-acetato and μ-pyrazolato ligands.[7] Cobalt(II) acetate tetrahydrate enhances the reaction rate of oxidation of 1,4-dihydropyridines using hydrogen peroxide to the corresponding pyridine derivatives.[8]

Cobalt(II) acetate tetrahydrate may be used in the preparation of [Co₃(OH)₂(H₂O)₂(aptet)₄] (aptet = 4-aminophenyltetrazolate)[6] and new tetradentate cobalt(II)-Schiff base complex.[9]
