Nickel(II) acetate is the name for the coordination compounds with the formula Ni(CH₃CO₂)₂·x H₂O where x can be 0, 2, and 4. The green tetrahydrate Ni(CH₃CO₂)₂·4 H₂O is most common. It is used for electroplating.

Ni(CN) 4 2-= Ni 2+ + 4CN-. In Ni(CN) 4 2-, there is Ni 2+ ion for which the electronic configuration in the valence shell is 3d 8 4s 0. In presence of strong field CN-ions, all the electrons are paired up. The empty 4d, 3s and two 4p orbitals undergo dsp 2 hybridization to.

Synthesis and structure[edit]

The compound can be prepared by treating nickel or nickel(II) carbonate with acetic acid:

NiCO₃ + 2 CH₃CO₂H + 3 H₂O → Ni(CH₃CO₂)₂·4 H₂O + CO₂

The green tetrahydrate has been shown by X-ray crystallography to adopt an octahedral structure, the central nickel centre being coordinated by four water molecules and two acetate ligands.^[5] It may be dehydrated in vacuo, by reaction with acetic anhydride,^[6] or by heat.^[7]

Safety[edit]

Nickel salts are carcinogenic and irritate the skin.
