Yellowish to orange crystalline powder | [Uses]
- 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.
