Opis

General description

Potassiumtetracyanonickelate (II) hydrate, also known as nickel(II) potassium cyanide, isa highly water-soluble compound used in electroplating and as a reagent inchemical synthesis.

Application

• Electronic Structure: Study of the electronic structure of tetracyanonickelate(II) complexes, essential for applications in materials science and coordination chemistry (JJ Oppenheim, BJ McNicholas, J Miller, 2019).

Potassium tetracyanonickelate(II) hydrate can be used:

• As a precursor for the synthesis of Hofmann-type metal-organic frameworks (MOFs) with high open metal sites density.
• As a precursor in the synthesis of an anion-exchange resin for the removal of residual cyanide complexes in industrial plating wastewater.
